This game does not work with DXVK due to lack of stream output support in DXVK.
It should run fine if you set the following start parameter to disable DXVK:
PROTON_USE_WINED3D11=1 %command%
Thanks! I'll try to run with this command
PROTON_USE_WINED3D11=1x1 2018-08PROTON_USE_WINED3D11=1 %command%x1 2018-08
App crashes and make dump files.
