People, you don't need to delete and reinstall the game! I did it and it didn't fix the issue.
I copied and pasted a message that I posted 2 weeks ago. I looked everywhere online and the only solution that worked for me was this one. Moreover, It happened to many people.
There is a faulty card or are faulty cards. Find it/them and quicksell it/them.
You need to find the card (or maybe cards) that is causing the issue. For me, it was Jake Matthews (the redux one) that I got from a pack. After I opened some packs, I started to have that issue.
So, I knew it was one of the new cards I got. I downgraded everyone, clear my PlayStation cache, deleted, and reinstalled the game. Unfortunately Nothing worked. It was driving me insane in the brain !!!
Finally, I told myself "it must be a new card" because before that, everything was working fine. So I tried to upgrade all the new cards I had. I was able to upgrade everyone except that Jake Matthews card (an upgrade slot what missing). I got rid of it (used it in a set). Since then, everything is good. Good luck!
