Cubase 12 audio warp glitches

Upgraded to 12 a few days ago and already having issues and first problem I’ve encountered is trying to use AudioWarp in editor window. As I move cursor over the audio waves, it deletes the graphics and I also have no AudioWarp functionality.

I got rid of the same problem by uninstall all Steinberg stuff including Cubase 11 and reinstall Cubase 12.
(Don`t forget to export your profile before!! or you start from scratch with makros shortcuts and so on…)

And one day later the problem is back… as shown below deleting graphics and no Audio Warp in theSample Editor Window.
