Changing EA Account email breaks connection to game, leaving no way to log in

Hello,

I recently changed the associated email with my EA Account, which seems to have broken the connection between my in-game account and my EA Account. Trying to log in via the PC client or even webstore results in errors. I broke the connected to my Google Play account so I could access an old account on my phone while continuing to access my current account via the PC client, which I have been doing for several months with no issues until recently. I have tried contacting in game and EA support, but support has just repeated that I should "log out and back in again" until it gets fixed. Is there an actual solution to this problem, or is my account inaccessible now? I have screenshots of the player ID, the ally code, and proof of purchases for several purchases I made while the account was linked to Google Play.

Thanks
