Lost Main Account

Hello

I have a problem. I lost my main account, Brezelinhoo (2m+ GP). I was playing as a guest account and unfortunately didn't link it to Google Play or EA. The last time I tried to play was on November 12th. I tried logging in and ended up in the tutorial. I've tried everything. I restarted the game and even reinstalled it, but nothing has helped. I spent a lot of money on that account. Among other things, I bought the Galactic Legend Kylo Ren bundle, both Raven Lightspeed bundles, The Mandalorian Lightspeed bundle, and much more. 

I last played on my Xiaomi Redmi Note 14.

I hope I can somehow get my account back.

Thanks
