CANT EDIT LINEUP

I try to go to my lineup and edit new players that I just bought and I can’t get into my lineup. I’ve tried going to squads and editing lineup, tries going in h2h and creating all new lineup. I can’t access my lineup anywhere. Everytime it says, error server can’t process. I’ve restarted my ps5, closed app, tried everything. It’s frustrating spending money on this game and can’t even fix a lineup.
