I just tried starting it, works without issue with proton experimental. opensuse tumbleweed, Kernel: 6.4.12-1-default x86_64, Device-1: v: 4.6 Mesa 23.1.6 renderer: AMD Radeon RX 7900 XTX (gfx1100 LLVM 16.0.6 DRM 3.52 6.4.12-1-default)

As for debugging try sshing into your box and check dmesg or check the system journal.

Why do you want to switch if everything is working out for you with pop-os?
