Strange issue with notepad.exe under clean w10 install 20H2.610

Hello.

I have just formatted this pc twice now. It's having an issue where notepad.exe stops loading. You just double click on it and it seems to load but nothing happens.

I remember to see it working properly as soon as w10 was installed, but it stops working after a while. I do not have anything fancy installed so it is puzzling.

Tried booting into safe mode: No difference.
Tried disabling MS Defender real time protection. No difference.

I am now running AdwCleaner, Malwarebytes and something else (possibly a online ESET scan from PE environment), but it is a clean installation. It should not have any infection.

Ideas?

Windows 10 19042.630

PS - I also tried w10 Windows Update drivers vs manufacturer's. No difference either. Everything else is working as best as it should.

Hello Berton.

Nothing opened. Nothing visible. I am reinstalling for the third time. PC was previously using MBR scheme. I am now using GPT/UEFI. It should not make any difference. This time I am going to create Restore Points to find out what's causing the issue.

Ok. I think I have found the culprit after retracing all my steps.

It seems it is DISM++ cleaning procedure that breaks something, even if sfc /scannow comes clean afterwards.

I am reinstalling again *sigh* and I will mark thread as solved when I finish.

Confirmed it's DISM++ WinSxS cleaning what was causing the issue. I am marking thread as solved. Thanks.

What were the full commands / steps that were done?
What were they supposed to do?

It's the first option for cleaning WinSxS folder under DISM++
