Hmm, the process segfaults right after, so I assumed this was the cause. Looking at the output again, I think there's another unrelated issue that happens at the same time, where Vulkan is unable to start due to ERROR_INCOMPATIBLE_DRIVER.

EDIT: Yes, I was missing a driver. I had a driver installed (amdvlk), but that apparently didn't work, and vulkan-radeon does.
