I can’t seem to log into NHL 26 online

My PlayStation account is linked to an EA account with an email that is not mine and I cannot receive the login verification code.

I’ve tried logging into my EA account to try and change the email being used for playing online. However, because I can’t access this email, I can’t access anything. It says in order for me to change the email already being used, it would send me a verification code to this email even though I can’t access it. I’ve tried everything it’s suggested, including steps from ChatGPT and YouTube. If anyone else has ran into this problem and has an idea on how I can fix this, that’d be great. Thanks.
