That isn't the latest version of DXVK and the trace replays fine.
Still crash with lastest master (with wined3d works ok)

According to ProtonDB this works fine, please test if DXVK 1.5 works for you.
Delete GraphicsConfig.cfg from the game files and start the configuration tool with DXVK enabled
Tested for one hour and I have no issue at all...
no issues here and im on windows :\
