Windows Store doesn't run, apps say I should register

Hello!

I am not sure if there is already a relevant thread, please point me there. As the title suggests, Windows Store won't load and when I try to start an app (Microsoft Mahjong) I get an error message:

Microsoft Mahjong is currently not available in your account. Make sure you are signed in to the Store and try again. Here’s the error code, in case you need it: 0x803F8001

I tried to reset the cache with wsreset, it didn't work. I also tried to reset the Windows Store fro Settings, it didn't work. Here is a copy of what I did in PowerShell but did not work:

Any suggestions appreciated. Of course I would not like to reinstall Windows 10 or lose any data.

Thank you.

Allready tried these, nothing worked. Inplace upgrade-repair could not complete and reverted any changes... It looks like I have to clone v2004 back from my previous SSD and upgrade to v21H1 again...

As I have said at another post, I have replaced my 250GB SSD with a 480GB SSD some months ago. Thankfully, I did not delete my data, so I will clone back to the new SSD again and see what happens. If everything works OK, including the Windows Store and the audio (from another thread), I will carefully upgrade v2004 to v21H1 again and continue from there. If I still have problems (hope not), I will dual boot with my old SSD to have a working computer, while I clean install v21H1 to the new SSD. Wish me luck...

Murphy's Law striked again. It seems that my backup is somehow damaged, so I could not load Windows 10 neither from my old SSD nor my new SSD. Sh!t! I started a clean Windows 10 installation, thankfully I had done recently a full backup of my data. I'll mark the thread solved, but if anyone has any idea of how to fix the issue without reinstalling Windows 10, I would like to read about it. Thanks.

OK, new clean installation completed, everything works now, both the sound (see my other thread) and the Store. Thankfully I had done a full backup of my data a few days ago, so I missed nothing. As with every clean installation, I have to invest a lot of time to reinstall and reconfigure all my applications... It seems that once Windows Store is not working or the audio device is installed but not detected (see my other thread), the only solution is to either reset Windows or do a clean installation. Too bad... If anyone knows of a fix that avoids reinstalling Windows, please do tell!

Hello!

I just downloaded the Media Creation Tool 21H2 and using that the Windows 10 21H2 ISO. Before I dare to upgrade to the new build, I would like to ask if anyone had any weird incompatibility, such as losing access to audio/video devices (see my respective thread) or losing access to Windows Store. Any other issue? Please share! Thank you in advance.
