Research direction
Start with the attached steam-15240.log and the reported startup crash under Proton 6.3-5. Compare the failure with the listed NVIDIA driver, kernel, and PROTON_USE_WINED3D=1 results. Done would require identifying a reproducible Proton-side cause and a validated compatibility fix.
