Fifa 25 not loading or showing

@Onepunchxbox329 try all the steps here https://help.ea.com/en/help/faq/problems-playing-online/ like a DNS change to google DNS to reinstall your game and also try to disable login verification. https://help.ea.com/en/help/account/ea-login-verification-information/ Go to your EA Account Security settings.
Under Login Verification, select Turn Off.

I also recommend to make a forum post inside the proper section (FC25 and then technical issues) and explaining your situation there in more detail.
