Unable to Link Steam to New EA Account Due to Old Email Access Issue

I'm facing a major issue with my EA account. My Steam is linked to my old EA account, but I can’t access the email associated with it anymore. I want to connect my Steam to my new EA account, but it won’t let me because of the existing link to the old account. I’ve tried everything, but there’s no option to unlink Steam from the old EA account without access to that email. Please, I need assistance in unlinking my Steam from the old EA account so I can connect it to my new one. This has been really frustrating, and I need a solution as soon as possible!
