Hello There! Bug/error with purchasing

Today I wanted to customize some cars but unfortunately the game doesn’t let me purchase anything. It says “Purchase failed”. I have around 26 million in online mode so money is not an issue.
Moreover I noticed that my character’s clothes got changed and I don’t know why or how, I want to change clothes and after I press A it just does nothing. Everything worked perfectly til today.

I have exactly 100 cars in online mode (maybe that’s the max slot?). I tried to sell some cars but it doesn’t work too, it just does nothing. Any tip? I’m on Xbox Series X.
