Hi.
I looked at your crash dump file, and it seems that something goes wrong when it attempts to load the shader cache. No idea why this have happened, but I believe the files have been corrupted somehow. It should be resolvable by removing these files from your %appdata%/Roaming/Fatshark/Darktide folder:
- shader_cache.hans
- shader_library.pso_lib
- state_stream_library.pso_lib
Remove these files will cause the shader cache builder to run again and hopefully generate non corrupt files.
