Substance Painter is freezing at the starting on my second screen

Hi Folks,

I installed Substance Painter on my computer new, and moved the window to my second screen, which is a Huion Drawing screen. After I closed the application and reopened it, it gets a white screen and freezes. I'm not able to open Sub. Painter anymore.

Can someone help me or give me a tip how to fix this?!

Thnx
