Crashing

hi there recently after purchasing the game I have experienced regular crashing every time I play the Fc26 Ultimate team game mode, at first I thought it was my console overheating but it’s not as I’ve cleaned it out and put it in a better space. I then thought it was my wifi and it seems to be my wifi is only poor when I’m online game modes like rivals and UT Champions however I don’t understand how this is as I have a WiFi booster in my room and Ethernet plugged into it I have had no other issue with internet in any other game except FC26. I have also tried deleting the game and re installing it which seemed to work majority of the playtime until the end of the night. I would really appreciate help on understanding the issue I’m having and coming up with a possible fix, thanks a lot
