I just did a clean install of Ubuntu 20.04
Updated my kernel to 5.6 with the ACS patch
uname -r: 5.6.19-acso
Installed the amdgpu drivers via amdgpu-install (no errors that I saw)
Installed Steam
installed a few games to use proton
Nothing launches, the dialog pops up to say “preparing to launch…”, but then closes and steam shows the game stopped.
lspci -nnv shows:

Try kernel 5.10, xanmod1 is also a good option (again 5.10).
Its always a good idea to have a couple kernels installed, you can select your old one from the boot option if 5.10 doesn’t change anything or work out.
Also keep in mind NTFS partitions need special treatment to work with proton, and the compatdata folder should always be on a EXT4 partition (just use symlinking if required).
PS. I understand you got this fixed now… nevermind then, also its Vulkan not vulcan
Can’t find a patch file to build it from either. I’m thinking about looking through the older patch files and manually making a new patch file for the newer kernel, but I haven’t had time yet.
