I have no mods, I have Java 17, no ressource pack etc and it still won't work... Edit 1h later (after weeks of trying): I managed! I manually donloaded AMD Software Adrenalin Edition (for my AMD Graphic card) and it solved the issue. Tried everything else, even updated AMD via the Windows driver update and it hadn't worked. Hoping it helps others!

I did all of theses (it was a pain doing the last one) and my 1.20.1 still crashed, i don't understand at all, please tell me there's another way without doing something super complicated

you saved me, i had this own made modpack of 47 mods and i didn't know where to look, i checked every mod and found out where the issue was. not every hero wears a cape, thanks

I have a problem, Optifine and Mini maps work separately, when I connect them there is a game error, I have everything on the same version of Minecraft. I do not know what's going on.

1.20.4. The last 3 builds of optifine say "compatible with Forge 49.0.31" but that does not seem to be the case, it crashes just the same as this video is about. Not seeing anything on the internet talking about that either. *shrug*

I have java 21, do you think that if i delete java 21 and install java 17 would it work?

Thank you! It worked after uninstalling java 8. Didn't realize there was such a big difference in JDK and java

im trying to play minecraft on an older version bc thats the only version compatable with the mods im trying to use but i keep gettin error code 1

I've had a similar problem for a few days. It all probably started after the last launcher update. The game started sometimes and sometimes didn't, and "exit code: 1" appeared, and sometimes my computer restarted. However, we still managed to play occasionally for a few days. I have been playing for 4 years on version 1.16.5 with a permanent, unchanged mod pack. A few days ago it stopped turning on at all. All attempts ended with a computer reset. I uninstalled all mods except forge 36.2.39. Minecraft has started. I started adding one mod at a time. It turned out that the culprit was Inventory Tweaks. The game started for me with all the other mods. Today I tried to look for a similar mod to inventory tweaks. I found inventory profiles next. I installed it. Exit code 1 popped up. I deleted it again. The game stopped starting. I removed all mods except forge mod. The game does not start. I tried running clean version 1.16.5 without forge mod. The game does not start. I deleted all minecraft and reinstalled it. I ran 1.16.5 vanilla. I repeated the operation several times, because sometimes the game started and sometimes the computer was reset. I decided to install several other versions of forge 36.2.20, 36.2.29, 36.2.39, 36.2.34. Similar effect. I installed java 17. The effect is the same. Now I can't even run pure Minecraft 1.16.5 because it freezes and resets my computer. I don't know what to do anymore. The most interesting thing is that on the second, older computer, where the same minecraft 1.16.5 and the same mods are installed. To be sure, I only removed this inventory tweaks mod. The game starts. The difference between the computers is that the old one still has Win 7 (I have Win10) and the launcher has not been updated. (I play on the server with my daughter, so that's why I have the same Minecraft). Now we can't play together because I can't run minecraft with mods on my computer in any way. Can anyone help? I don't know what to do anymore, especially since vanilla doesn't even start. Please HELP.

i still have the problem even after all this. i only have this issue when running forge mods not fabric or regular Minecraft. HELP

does anyone know why i can only get 1.20.4 forge to work but not earlier versions? i wanna play 1.20.1 and have installed the 1.20.1 client numerous times but still cant get it to work even though i go through the exact same process as 1.20.4

In short, Minecraft support helped solve this problem. Personally, the problem I had was that my computer account name had an invalid "!" I quote: "There is a bug in Java's programming that makes it so if there is any alt code or special character in the name of your computer, it will not work properly. Basically, the program searches for files where it thinks they are but cannot find them. This isn't anything to do with the game, but the Java Runtime Environment itself." I personally solved this problem by reinstalling Windows and creating a new name, since to change a nickname you need to delve into the computer’s registry, and this can cause errors and crashes in the system. It is also possible to create another account with a name from A to Z without any characters, and this problem should not occur when the game crashes. I never thought this would be a problem, funny.

I have updated every single mod, and before it didnt give any trouble, but it randomly started doing it now, i have done every posible solution and still it crashes with error code 1 HELP

Thank you so much man, I was getting so mad tying to figuring this out.. you save me🙏😭

i had the same problem so i changed to iris and sodium, few months later i didnt change anything and it works somehow BUT now my friend has the same problem, tried without mods and reinstalling the game updating drivers but nothing works

⁠i need help, I can’t play this versions on curseForge(a place where you can create modpacks and download modpacks) which are 1.19 and 1.20, i have Java 18 which is the most recent version, i have no mods on the minecraft default folder, i find really strange, pls help. If you need more info just ask

What helped for me was to go into the Nvidia Control Panel and run Minecraft on the GPU (which should automatically happen but apparently it didn't?).

Thank you very much, I watched several videos with different solutions and I hadn't thought that the reason would be the mods

i have java 21 and none of these fixes are working for me.. i have no mods in the folder and followed all the steps but i checked my java and its the most recent one

no matter what i do even just pure forge won't open and i get the code 1 error every single time (i've tried like 3 tutorials)

for some reason, i was able to play 1.20.1 forge version. but now i couldnt. only below that version i can

no mods just forge for 19.2 and wont start nor will curge forges app for mods so idk

Thank you so much!! All i needed to do was reinstall optifine, delete forge and reinstall it again!! Then going one by one, check the mods (in my case decocraft) that crash the game

so im still getting error one i have zero mods on my new pc i have tried both java 17 and java 22 dev kit reinstalled forge and java even Minecraft and i dont believe it to be my driver which is a Radeon RX 5500 XT

I was able to load the game and play with mods on 1.20.1 and then I installed optifine and it stopped working with exit code 1. I got rid of optifine and took all the mods out of my mods folder and forge will still not work.

Question, does it have to be 1.20.4? Or can it be any of the forge instances?

i want to play forge in multiplayer but it says multiplayer is not available

How do I get forge on my like installations?

Nope. No mods in my folder, deleted the .minecraft folder, uninstalled and reinstalled minecraft, got rid of old java versions and installed the one in the description, deleted the forge version in the launcher, installed it again for the correct versionand still exit code 1 crash.

you are a real chad for helping me out ;D

Hello, i would need further help por favor :') I have the latest version of Java and forge, i usually play with BMC2 or 3 with curseforge and it works fine. I tried to install BMC4 on my computer and my GF's one. It works on her, so does my BMC4 server (which runs on my computer). BUT my own game keeps crashing with code one even after following everything was advised in this video. Can someone help please ? Btw, if it can be of some help my graphic cards are : "AMD Radeon (TM) Graphics" and "NVIDIA GeForce RTX 3060" i don't know a ship about these things so i don't even know if what i said makes sense but anyway... Please someone help my poor soul :")

I'm planning to make my own Minecraft series with the Create mod along with other mods, like the Adventure Backpack mod as well as Cracker's wither storm mod. Unfortunately, I can't get onto Minecraft forge 1.20.1 because of the freaking Error 1. I tried everything to make it work ranging from reinstalling Minecraft to getting the newest version of Java and the drivers are already updated, and yet Minecraft Forge 1.20.1 is still NOT WORKING!!!!

If u find the mod thats causing the problem u just dont use it?

i have no problem running on different launchers same mods.

i have java 22 but its not working

i was using java 8 on a 1.20.1 version through forge and it was working just fine

Thanks, It was the optifine one that got me.
