I am in the process of setting up NixOS on my desktop to be my daily driver, however suddenly no steam games are able to launch they were working until recently (reverting to an older build didn’t help), they load vulcan shaders then attempt to launch before crashing with no errors.
Currently this machine dual boot with windows until I iron out most of the kinks. NixOS is configured with flakes and home-manager(standalone) but steam is set to install system wide in the main config for multiple user access. I had been testing with games installed on the windows drive. they would load but had crackly sound, now they just don’t load. No issues with the installs they still function in windows.
I should note that modrinth also crashes when launched but I do get an empty window briefly first.
