The minecraft launcher thinks that there is no internet and plus it thinks that I don't have a single mojang game on my account (although I have 2 versions of minecraft). This error only applies to the new version of the launcher (which is in the Microsoft store) and everything is fine on the old one.

Hello, I independently solved this problem over which I racked my brains for 2 months. It turns out I just had to log in through a different microsoft account. Thank you for trying to help.
