EC:105 Error - Game Randomly Closes and Shows "Go Online"

I have an issue with EA FC 26. While playing, the game suddenly closes without warning and the EA App shows an error with the code EC:105. After this happens, I also get a message saying "Go Online," but I am already online.

This happens randomly during gameplay and makes it very frustrating. My internet connection is stable, so I don’t think it’s a connectivity problem.

Has anyone else had this issue? Is there a fix or workaround?

Thanks in advance.
