Hi,

Since the latest patch I have been unable to log in via the launcher (official Windows launcher launched via WINE).
When trying to log in I get the following message:
"This service account does not have a valid FINAL FANTASY XIV license for this platform or your subscription has expired."

However I am trying to launch via the same platform that I have played on previously, and my subscription is still ongoing.

There's been several Reddit posts by people running into the same issue on Steam Deck and other desktop Linux distros so it looks like the latest patch has prevented most/all Linux users from being able to log in.
