Sim Update III deleted MSFS

I’ve gone to update MSFS this evening by opening the game from desktop in the normal way.

It told me a mandatory update was available for download via the Marketplace. Upon clicking Ok, the game exited to desktop and opened up Xbox App and started to download MSFS as if it hadn’t been installed before.

Upon looking, the shortcuts were gone and all MSFS directory files had been deleted.

Huge issue - has anyone else experienced this?

The files weren’t deleted, but the game wouldn’t launch.
I had to download from marketplace again (a very short download) to fix the issue here.
