Why has this still not been fixed? Still happening after the RetroWave update and the only way I have found to avoid it is after launching FH5, hit the X button and end game and re-launch it.
This does mean the game boots up from fresh but less annoying than the alternative.
This has been a problem for as long as I can remember. Never use quick resume for any Forza game. If you see it pop up when starting your game just go ahead and quit, restart. Matter of fact always quit game when hitting that power off button.
