I saw this topic yesterday almost as soon as it was created, so did not start MSFS 2024 over the weekend.
Since my Windows / MS-Store / Xbox Apps settings all have automatic updates disabled, I avoided having the update being applied in the background.
I have now followed the instructions in Official Microsoft Flight Simulator > News & Announcements
And MSFS 2024 has started without any issues. All my graphics, controller and other settings are intact.
