I can confirm this crash also on Fedora 43. For some reason this game only gets past the Santa Monica Logo on Linux when using the AMDVLK driver. However that project was abandoned by AMD to focus on RADV. Here is a log up to the intro video with AMDVLK. I hope this helps a developer with debugging.

Looks like shadps4 emits invalid spirv that's not caught by the validation layers: https://gitlab.freedesktop.org/mesa/mesa/-/issues/14076#note_3254344
