Keylogg

I guess no, thanks for your time and help! 🙂

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 debug.log

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. debug.log launcher_log.txt

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?

My bad. Here you go launcher_log.txt

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. debug.log

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.

I hope that this is the correct one. launcher_log.txt

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. debug.log

Obviously. But that only happens when i try run Forge with mods installed, when i remove the mods it works.

Well the thread is called "Error Code 0", and i get the same "Error Code 0" when i try to launch Forge with mods installed. "Exit-Code: 0" to be more specific.

So i ran into the same issue. I have tried everything but nothing works. I am only able to launch the game when there are no mods installed.
