Since the update version 16.0 to 17.0 I have big problems with my windows VM. When I leave the mac for more than 10 min with the screen locked two things happen: in some cases the VM shows a window that no longer responds to the mouse or keyboard but resumes if I maximize and resize the screen. In other cases, however, the virtual machine screen appears black and I just have to force turn the virtual machine off and on again. I tried to solve by field reinstalling the mac (Big Sur) and parallels (17.1.0) but it didn't solve. Someone can help me?
