FIFA 26 is impossible to play!!!

FIFA 26 is impossible to play!!! I like to set up my main squads before starting my coaching career! I add some players to my squad and assign free agents to my teams. But now it's not possible. I go to the menu, select "Manage Teams," then "Main Squads." I change the squad as I see fit, exit the game, and nothing is saved!!! Also, if I go to the team management - transfers in the club, I add the players I want to the team, such as free agents, before starting my career, but the game crashes and I can't make the replacement! I'm playing, I choose to replace a player, but nothing happens! I can send you a video if you need it. This error has been present since FIFA 25! You constantly encourage people to report errors on the forum, but this error has been present for two years, and nothing has been done about it! What is the issue with EA? The best specialists can't fix one mistake? That's ridiculous! The game is not enjoyable at all - it's just a waste of money!
