Steps to reproduce

Create a instance with forge, maybe some mods and start
Boom, You get this error

Suspected cause

I just installed Archlinux instead WIndows
System error or Path error maybe

This issue is unique

• I have searched the issue tracker and did not find an issue describing my bug.

This isn't a bug with MultiMC, but rather game support.

This is a bug tracker for MultiMC, and therefore not the appropriate place for game support. There are many communities which may be able to provide game support for you - the MultiMC Discord being one, but also the Minecraft subreddit, Minecraft Forums, the #minecrafthelp IRC channel, and potentially many more.

I just found out I'm using Java 17
I installed Java 8 so it's working perfectly
Thank you anyways
Have a good day
