Showcase locked me out

So, I downloaded the Showcase version before its retirement and now ever after it's retirement I can't play on new generation version of FC 26, all i can play is Clubs, Kickoff and the Training Arena, Ive deleted the game on several occasions and still can't play on it, Showcase won't delete and it's a big problem

How do I delete the showcase version, it doesn't give me an option, all it says when I try and delete is "Add-on, doesn't need to be installed" but still won't delete
