I posted a message in another forum, but I haven't received any responses yet. I'm posting here too, to give it more exposure. I'll leave the link instead of retyping all the information.
Control Panel: Computer selection causes (Not Responding) | Windows 10 Forums
W10 Home Version 21H1 (OS Build 19043.1237)
Eh, created a local account. Ran through the same scenario to repeat the problem. Same same. I'm moving on. I'm just chasing weeds with this one. The good thing is, all devices are installed cleanly and no reported problems. File Explorer (explorer.exe) hangs on this one step, so its a software issue that will probably be resolved in the MS patch down the road. Maybe this is a bug they aren't even concerned about since they are trying to retire the Control Panel all together.
I gave in and did the in-place upgrade this morning. That actually cured the Windows Explorer hang when I touched the icon that displayed my PC in the Device and Printers applet. Strange why that happened and having to do the IPUG to cure the problem. I guess if all fails Microsoft gave us at least on solution that appears to work every time its tried.
It could be that you had Explorer and maybe other files were corrupted.
The in-place upgrade reinstall Windows and all files.
There are some system / files check that you could have performed.
Open a CMD window as administrator and type:
chkdsk c: /f
It will say your disk is in use and ask if you want to schedule to next start = yes
Restart
Pay attention on the results, specially bad blocks, bad clusters, bad sectors etc
Back to windows, open a CMD window as administrator and type:
SFC /scannow
and
Dism /Online /Cleanup-Image /ScanHealth
and
Dism /Online /Cleanup-Image /RestoreHealth
