@169Romero_@XBOXSupport I had this issue and I was able to find the fix if you are playing on PC.
I wrote some instructions on what you need to do to get your game working again in a Steam Discussion post.

Hope this helps you!
@Spc___@XBOXSupport Yes it happens on every platform you can play FH6 on. Even FH6 on Steam still uses Xbox’s cloud saves and not Steam Cloud Saves. You should backup your save files so you have something to restore just in case Xbox cloud saves decides to delete everything.
