Hey there VierteNach6,

Sorry to hear about the app loading issues. Have you tried to uninstall the Xbox App and reinstall it yet? That can help with this issue.

Keep us up to date!

I get the same issue but only on 1 pc, Reset Windows Stored app and Uninstalled and uninstalled Xbox Console Companion and stil unable to login (0x409) error.

Unfortunately, the resource you shared does not have a solution for the issue I am facing (basis the image above). Every time in click on the sign in button, there is a window that pops up for a fraction of a second and then disappears
and the error code (0x409) 0x80080300 shows up below the sign in button.

Would you happen to have some other solutions for me to try?

Thank you in advance!

The methods below didnt work.
