TF2 product key disappear from game properties and game runs on trial mode

Hi, folks! I need technical support.

I can't play Titanfall 2. I own the game since 2017 but last weekend it started to behave like If doesn't own it. 

When I try to play it shows "trial" and the message "Purchase Titanfall 2".

I realize the product key is missing from game properties. All other games have their own product keys there, even Apex Legends.

I tried to fully remove and reinstall both game and EA App, clean all the Titanfall 2 related keys on Regedit, but no success. I believe its an account issue.
