Hello @spagoc, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/943#issuecomment-981093173.

On my PC, after the 2021 November update, "Hellblade Senua's Sacrifice" stopped to work giving the following error:
DX12 is not supported on your system. Try running without the -dx12 or -d3d12 command line argument.
I don't know if there is a workaround to solve the problem.
