Hey Fatrichy34578,
Just to be clear, you're trying to log into the same EA account that's linked to your PlayStation account currently, right? It's just that you no longer have access to that particular email address?
That should just be a matter of verifying some details with our support team so they can help update that email address. Just be sure NOT to unlink your PlayStation account at any point, especially if you're trying to play on PC with everything you've earned already. Unlinking can result in losing that progress, as it's stored on the EA account level rather than on your actual PlayStation account. So, if you were to unlink that PSN to link it to a different EA account, your progress would not transfer with it.
Instead, if you're not able to update your account information with these steps, you can scroll to the bottom of that page and hit the Contact us button to create a new case so our support team can take a look. Thanks!
