Hmm... I don't know what could have been. It crashed even after a clean install, for no apparent reason, and those crashes have continued in PopOS, NobaraOS and Tumbleweed aswell. Maybe I'm doing something wrong.
Sure. It'a a Lenovo Legion 5 Pro. AMD Ryzen 6800H and NVIDIA RTX 3070.
I think the issue might be with the AMD Radeon integrated graphics, but I don't know what else to do but use WSL or pray it doesn't suddenly reboot while using PopOS.
