drivers are up2date

the problem first occured while maya was running
I created a new scene and wanted to adjust shading settings like I always do but nothing changed

so I discovered that twhen using the auto unwrap tool the problem somehow fixes itself instantly and I can open/create a new scence and everything is still working but as soon as I restart maya the problem is there again
so for now I have a workaraound but still hope I can get to the bottom of this I want to avoid to do a fresh windows installation
because as I said it was working at first but then suddenly this problem popped out of nowere
