[Linux] Game will not start in anyway through the launcher.

[altoryus]

Describe the bug Opened appimage r2modman and installed all mods I wanted, included core ones like BepinEx and R2API, but when I click on either "Run Vanilla" or "Run Modded" I am prompted with an error, shown in the image.

To Reproduce Steps to reproduce the behavior:

1. Open R2Modman Appimage
2. Install desired mods
3. Click on "Run vanilla" or "Run modded"
4. See error

Expected behavior To run the game with all mods through the mod manager.

Screenshots

Additional context I do not have any issues to open the game through steam normally. I'm using Linux Mint Cinnamon and running steam through the flatpak installation.

I had the same issue, but I installed this package lib32-mesa on Arch Linux and it helped me.
