Please read the FAQ, it has the solution to your issue - both where to find your logs and how to fix your issue.

Remove the server-1.20.1.jar file - it's not Forge as Forge 1.20.1 doesn't have an executable jar - you need to use the run.sh.

Uninstall all versions of Java on your PC, reboot, then follow the guide in the FAQ

Forge doesn't touch anything OS-related beyond what vanilla Minecraft already does. Your issue sounds highly coincidental and likely caused by faulty hardware or broken drivers. For testing faulty hardware, check the SMART details of your boot drive, undo any overclocks, check temps and do a memtest. For fixing broken drivers, follow the guide in the FAQ, especially the last point regarding the clean uninstall utility.

We need the crash report or debug.log, as explained in the FAQ

All the Forge installers have been fixed - if you redownload an installer from the Forge files site it should work. The last updated reflects when the build was published, not when the installer for the build was fixed (otherwise it would show as ~4.5k builds worth of Forge all being released today :P)

Follow the driver update guide in the FAQ
