National Team Sheets

I edited the National Teams on customize, not career mode. I was putting different players than the ones usually on the team. Then once I go to edit the team sheets and as soon as I move down the columns from Nation to League to Team. The first team is Argentina but as soon as Argentina gets highlighted, the game freezes, it doesn't let me go right or left or back up or even click on the team to edit. THE GAME JUST FREEZES, GOES BLACK, AND THEN KICKS ME OUT. So I can't ever edit any national team's team sheets until this problem is resolved.  

Thank you for taking the time to read this, please resolve this issue as I want to enjoy my time on FC26 but I can't do it if I can't make it mine and/or if I have to keep resetting all of my teams.
