Hello @mackatozis, we're using one issue per unofficially supported game title, and usually I'd transfer this issue report to #4125, however, this specific issue is that your video driver is too old for VKD3D-Proton in Proton Experimental (012c:err:vkd3d_init_device_caps: KHR_dynamic_rendering is not supported by this implementation. This is required for correct operation.) which is intentional and not a bug in Proton.
Please update your video driver to 510.47 or newer.

Today, on the 13th of May, 2022, my steam client updated to the latest Proton Experimental

Force the use of a specific Steam Play compatibility tool -> Proton Experimental
Temp Solution
I changed the Proton version to
7.0-2and the game boots normally.
