Can't launch IL2CPP linux games

[claymorwan]

What happened?

Everytime I try to launch a native IL2CPP Linux game with BepInEx, I get and an error when initializing metadata then game crashes with an terminate called after throwing an instance of 'PAL_SEHException' right initializing the chainloader It did generated the configs files but can't launch no matter how much I try. Btw I set the BepInEx distribution to stable but it also does the same thing with the BleedingEdge ones, I wanted to try with the BepInEx 5.4.* versions but I couldn't find their IL2CPP linux verions.

Steps to reproduce

1. Follow the IL2CPP Linux game installation guide and set executable_name=""; to the right executable name in the run_bepinex.sh file
2. Run run_bepinex.sh through terminal (steam doesn't wanna even tho I'm doing it exactly as said in this page of the wiki)
3. Watch as it dies

BepInEx Distribution

Stable from GitHub
