Windows 10: Micrsoft store, won't install, Xbox app won't install, defender doesn't work - all after...

I'm at my wits end and thoroughly hacked off. I upgraded to Windows 11, what a mistake. Microsoft Store wouldn't work. So I tried all the suggestions I could find on here. Powershell scripts, wsreset, troubleshooting, Store repair and reset, uninstalling xbox app, Reinstalling Windows 11. Nothing works. Except now, after trying these steps, Microsoft is no longer installed and nothing I do will reinstall it. Xbox app is uninstalled and will not reinstall. Windows Defender doesn't work. I tried 'Go Back', hoping it would take me back to Windows 10, nope, did nothing.Please someone help

For some reason my one computer won´t log on to the Xbox app and OneDrive. My other computer on the other hand works perfectly fine. I can´t seem to find to reason and even tried with a factory reset and still the same issue. Help?

I´ve allready tried deactivating the firewall and even rebooting the computer
