How can I fix an infinite loading screen on Forza Horizon 4?

Playing Forza Horizon 4 on Xbox series X, I tried to download and apply an online design to my car. The game displayed the "downloading and saving the design" message... but it got stuck there. After a couple of minutes I gave up and restarted it from the Xbox menu.

Now, when I start the game, it cannot complete the loading screen. It's not frozen, my statistics keep rotating on the bottom... but it never loads.

I tried, without success:

Waiting over 10 minutes, in case it was just slow.
Hard resetting the Xbox (completely shutdown, then wait a couple of minutes and reboot).
Deleting my data and resync'ing from the cloud.
Deleting and reinstalling the whole game and the DLCs.
