Why don't Microsoft programs work correctly on my laptop?

Question

У мене не заходить на мої користувачі (тобто аккаунти)
не працює майкрософт сторр
та некоректно працюють офісні додатки та програми
навіть сюди не додає скрін помилок

---

Translated from Ukranian to English:

I don't have access to my users (ie accounts)
Microsoft Store does not work
and office applications and programs do not work properly
doesn't even add an error screen here

Answer 1

Log off current account and switch to another local account, test those programs and Store.
You could login https://account.microsoft.com/ to see if there is anything wrong about your Microsoft account.
If still no help, try to use the original 20H2 image in-place upgrade system, this way will fix system related issue.

Hello,

What version you're currently on?

For multiple issues, try to perform Reset by keeping your data:
