My MSFS Install starts to work and then fails! Help Please!

Repeating ...

- uninstalling and reinstalling MSFS okay,

- installing FSUIPC MSFS okay,

- rebooting the PC MSFS no start

Correction .....

Its not FSUIPC that causes any issue.

After rebooting the PC MSFS does not start.

I've resolved the issue. The cause of the infinite loading screen/connectivity was a result of MSFS failing to connect to my Xbox profile. There was a post by another user(rysslass) that describes the steps on how to resolve this issue. Going to copy and paste it here.

I had the same problem. It worked after I started MSFS with XBOX app and when I got the error switched back to XBOX app, logged out, not closed, and switched back to MSFS and tried again.

Hi Jesse,

I'm bummed! MSFS started loading then said to go to Microsoft Store and get the patch - then MSFS seemed to remove itself and TILE from my PC start menu like it never existed! Help...?

I don't even have WIFI in my desktop PC, it's gigabit ethernet all the way and it still doesn't work.

Edit:

I went to "Reset this PC" in Windows 10, wiped everything (clean install), installed only Google Chrome and Steam (no drivers or other software), installed MSFS from Steam and it still doesn't work. The problem is definitely either in MSFS itself or with
their servers.

I've tried all the suggestions you posted and my MsFS just hangs on the loading screen. It started before the new su10 release for me. I decided to upgrade my NVMe hard-drive to 1TB. This past weekend I installed windows 10 and installed all updates and drivers. Then installed MSFS on this fresh hard drive with fresh windows install...and after installation I have the same issue. Background music is still playing and the blue bar is all the way to the right. I've checked my hardware and all is functioning as expected and no high temperature issues.

Been trying all week to get this to work. Very disappointed.
