nvrun log error

Using prime notebook
Using dxvk
Starting Battle.net with 
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia wine
Battle.net.exe
It shows login screen, then closes with error (@see attachment)

Running w/o nvidia shows launcher, no game could be started, no error in log.
Tried clean WINEPREFIX, tried w/o dxvk with same error.
Using wine5.6 to run the app works flawlessly.
