Need for speed unbound save file problem on xbox series s

hello my problem started a day ago at night around 11. First of all the game couldnt load my save file it just went up and up. After 5 minutes i closed the game and re-opened it. It loaded my save file but i cannot go to online. It said to me that: your inventory couldnt be loaded. It somehow got fixed but now i lost a lots of stuff like rims etc from the older speed passes. I literally unlocked everything in the game and it says to me 'item locked' also have the ultimate collection upgrade. Please fix this because i payed for them.. thank you!
