This doesn't solve the problem - I did a clean reboot. After that, the laptop restarted more often. Started a new installation with download over the network and after that, the laptop shows only circles and restarts again - saying for a millisecond "we
will make everything ready for you". This is happening all the time. My device has been bought at 3rd of January 2020 and has been replaced a short time after delivering. I think, MS really has a problem with the design of the motherboard. The same Ryzen CPU
is running perfectly on other devices (and motherboards) I have with W10 Pro, running the same applications.
I have had no problems until the 2H20 update. After that (12/20),
every program is hanging, lagging or (mostly) the computer just shuts down. Used programs: Office-Applications, Citrix, Anno 1800(can only be played with absolutely no special graphics, respectfully), Anno 1404. I used the computer the same way for a
year.
