So here is my problem:

when i try to Launch the game via Forge version "37.0.39" with mods installed, i get the error: "Exit-Code:0". But when i delete the mods it is working as normal. And yes the mods are for version 1.17.1

Even after a fresh install of Minecraft (delete the .minecraft folder and deinstall) and Forge, it still does not work.

Post the log from the launcher window as well.

I hope that this is the correct one.

Refer to the Optifine downloads page regarding compatibility with Forge. At this time they have not released a version that is compatible with Forge.

Well, it doesn't work either when i remove Optifine. It only needs 1 mod to be installed and it won't launch, doesn't matter which mod it is.

Post a debug.log without Optifine installed.

So i have updated Forge to "37.0.32" to see if it works, but no luck so far. Here is the log without Optifine.

Are you using the Mojang launcher? Did you use the installer to install Forge?

Yes i am using the Mojang launcher and i installed Forge with the installer. I don't like using 3rd party launchers. I just tried another clean install, still the same issue 😑 Could it be my java version i am using?

Just now, diesieben07 said:

You are using the launcher built-in Java, which should work fine. I don't know what this error is, it's FML just failing somewhere during startup. Does this happen with no mods installed?

No, if i launch Forge without mods installed it works fine, but as soon as i install just 1 mod the game will not start anymore. Here are the logs without mods.

Okay, please install just one mod and post new logs. Also post the link where you downloaded that mod from.

This one is a classic, so i just tried to launch Forge with 1 mod and it worked... Tried with a few more mods and it worked again. I don't know what caused it to not launch before 😤 I download mods from CurseForge.

PS. Can't upload launcher.log because it is to big

Well, if it works now, do you need any more help?
