FC 26 crashes when connecting to EA Servers on Steam

Hello EA Support,

I am experiencing an issue with EA Sports FC 26 on Steam.

The game launches normally and works perfectly in offline mode. However, as soon as it starts connecting to the EA Servers, the game immediately closes to the desktop without any error message.

I also noticed that in the FC Companion App I receive the error:

"An error occurred and your Squad was not saved. Please try again later."

This makes me believe there may be an issue with my EA account, Ultimate Team club, or cloud profile rather than the game installation.
