NFS Unbound - error code "FTCL50001"

@EA_Illium I already have in my first post here, with a possible reason why it's happening, but just to be sure I'll do it again

Platform: Xbox series X

Tag: Doryzzkendy

Region: Australia

Error implied: yes, non stop since first getting it

Date of start: a few days after Vol 3 update

Anything else: Slow sync on startup and randomly giving already unlocked items from EA play, speed pass and pre-order bonus

Attempts to fix: Checked Nat type, didn't work, restarted console, didn't work either, restarted game, didn't work as well, uninstalled and reinstalled the game, again it didn't work.

Possible reason: Item overflow due to a few things I noticed. One when the game goes to Synchronise with the online servers, it takes way longer then before the issue (roughly 2 to 5 second before issue, now roughly 1 to 3 minutes of waiting for it), Two every so often when I load into the garage before finding a server it will give me everything that I already own again which might be duplicating them (Items in question being the EA play cars, all speed pass items currently unlocked and pre-order bonuses) which becomes annoying to see the "New" tag everywhere when you go. And three I tested it if it was the game itself or my internet by loading into a account that has nothing on it and the game doesn't come up with the issue then, so account items have to be a main cause of the issue.

Even though I've already posted this, if it help fix it, then it need to be done since I've been playing since the palace edition early access and have around 25 days worth of gameplay on Unbound.

I hope what I've found is the reason why it's happening
