Menu lag and constant unstable connection FC 26 PS5

The menu is stuck at loading for 30 secs or more whenever an sbc is completed, rewards claimed from obj, conducting player search during sbc and accessing store. There is an error that says unable to connect to fc ut server and when I click on ok it gets me to main menu screen and I have start over again. This is only happing with one account as I have no issue when I switch to my brothers account and play the same game on same settings. This started exactly from Thunderstruck promo and It is getting worse. Im unable to finish sbc or play rivals or champs cause of this. 

Is there any resolution to this?
