Not reproducing a crash with the demo on Linux/with Proton using Intel or AMD.
Does current master behave the same? You can download a build here https://github.com/doitsujin/dxvk/actions/runs/18042917510
Same with master, seems to be a windows or nvidia issue then.
Don't know if the logs are any different, but here.

Doing some poking here it seems that i am able to get the demo to run with dxvk on Windows by either forcing it to run as administrator or setting up DISABLE_VK_LAYER_VALVE_steam_overlay_1 in the environment with a value set to 1.
In event viewer the following can be observed when it crashes

Yup, executing directly does not crash.
Steam shenanigans, it seems.
Should this be reported to Steam or is this something can be fixed with DXVK?
It is unlikely that this is something that can be fixed in dxvk. Seems like it might also be exclusive to Windows
Crashes on startup, works fine without DXVK.
