Windows not booting on OC

I successfully switched to OC from Clover (which I don't really understand what the benefits are) with a working Catalina.

My problem is that windows doesn't boot. I can boot Windows just fine if I press F11 while booting and select windows over OC, but if I select windows FROM OC, the little circle spins half way and it freezes.

As always, any and all help is greatly appreciated!
