Marketplace update ruined my game!!!!

I don't understand it completely but with the new update the steam and EA connection is not working. This affects the game to access the DLC packs that I PAID FOR. Marketplace shows the DLC to be deactivated because according to ChatGPT the marketplace UI cannot read the lisence when it is purchased through the EA app or the Steam servers which is ridiculous. I tried to solve the issue with ChatGPT all day and it is not working!!!! I would really appreciate any help at this point, I don't care about the saves as well I don't even want to use mods or CC anymore I just want to open the game that I PAID for or maybe just get a refund for all. I restored everything to an external drive at this point to save my computer from this nightmare.
