As far as I can see now, it is due to my Windows 10 installation. I reinstalled Windows 10 on an empty SSD. Everything runs. Maybe an installed program is causing the problems, or a setting in Windows itself. I will reinstall everything the days and test after each step. Thank you for your help. …

Maybe it's on the motherboard? It's the Asus ROG STRIX Z590-E Gaming. VT-X is enable.
