Question Error code 0x80073cfa

[PaallikkoYoda]

I'm on windows 10.

I had on my taskbar apps I use all the time such as Spotify and Whatsapp.

Yesterday Spotify stopped working, today WhatsApp stopped launching too (other apps are still opening so far):
When I click nothing happens, when I try to launch it from the searchbar, same, and the icons are "grey".

In the App settings, there are no updates to be made.

I can't reset the apps ; It says when I try resetting the app: "We couldn't reset this app. Try again in a bit."

Also I can't uninstall it. Error code: 0x80073cfa.

I tried uninstall it with PowerShell: it still displays the same Error.

Both apps are still working on my phone.

I ran CCleaner, cleared caches, restarted...

Edit: I also have basic windows apps I never use, no longer working, as Calendar, Mails.

What can I do to make it work, or at least to uninstall, reinstall?
Hopefully without having to restore factory settings.

Thanks in advance.

malware scan the system?
