I found a solution on Reddit which worked for me.
Log into the game, disconnect from the internet, reconnect, go back to Unbound and make sure it's in offline mode, and then click to go back online. It should reinstall all the inventory correctly this time. At least, that's how I fixed it. Got the issue a few days ago and that's how it stopped.
EA Staff (Retired)Unlocked cars I must have at least 100, although I have only 3 in my SP garage and 115 in my MP one. As per wraps, I don't think that I have any more than 45
Keeps kicking me out of MP even if neither Error F03 or FTCL5001 appear, extensively synchronizes the inventory every time I reconnect (it disconnects me from EA once it kicks me back to the main menu), and now even the progress bar broke?
EA Staff (Retired)Passing this on for the team to be aware of, if the steps we've previously shared are not we may need to wait for a future update.
I have this same error and can’t play online now
