Windows 10 hangs on start up screen

[Pascalv2]

I installed Windows 10 as a Boot Camp partition first and then installed it as a VM using Parallels 10.
This functioned normally, until yesterday. That's when the problems started: when I start Windows 10 in Parallels 10 it hangs at the start up screen, with the dots circuling endlessly. When starting directly in Boot Camp it functions normally.
Weird thing is also, that when downgrading Parallels to version 9... Windows 10 functions flawless.
When upgrading to Parallels 10 again, the above mentioned problems start again.
So now the only way to have Windows 10 running as a VM, is by using Parallels 9.....

Any solutions for this?
