Invalid Session And Or Error with account Popup

Ive Tried to Restart My Switch,Redownload the game,Check For Corrupt Data,Sign out and sign in again and nothing is working,this keeps popping up regardless of what i do,It is either Invalid Session or Problem with account and my Player skin never loads,I know there is nothing wrong with my account because ive also played on windows 10 version and that happens rarely but it still happens
