Error Code 105-80190000

I just purchased the full version with friend pass bundle of It Takes Two for Nintendo Switch

Whenever I try connect online I am getting a notification that says “You account settings have changed. Please connect again now. Code: 501-80190000”

this just repeatedly pops up over and over. I have read all the help desk articles on how to resolve and nothing has worked. Unlinking/relinking, remove/redownload, adult account, brand new EA account not linked to anything other than Nintendo.

I bought this specifically to play with friends while I go through chemotherapy/a transplant and I feel like I got ripped off 

went in circles with trying to contact EA directly with no luck. Honestly just want a refund at this point but it wont let me do that either. 

Please help :(
