Hello @xxkfqz, it looks like your system is configured to use AMDGPU-Pro. Can you test how these games behave with mesa/RADV? Also, please copy the contents of Steam Runtime Diagnostics from Steam (Steam -> Help -> Steam Runtime Diagnostics) and put it in a gist, then include a link to the gist in this issue report.
@kisak-valve Steam Runtime Diagnostics
Steam client seems to have a random issue. Closing the client and starting it again (without rebooting) seems to solve it sometimes.
For me this appears after computer has been rebooted (which doesn't happen often). Restarting Steam seems to fix whatever it is.
@kisak-valve Yep, removing AMDGPU-Pro drivers makes all games run again
Looking over the diagnostics information, looks like VK_ICD_FILENAMES was forcing the Vulkan loader to only try a single option, and since that didn't exist it broke all Vulkan render paths.
