Suddenly getting "Mail Cache Error" in game

I’m playing EVE with the stand alone official client using Lutris and Linux Ubuntu Studio 25.10. It works great, and when I first played last week, in game mail worked perfectly. Suddenly, starting about 3 days ago, I’m getting a “Mail Cache Error” whenever attempting to access in game mail.

I’ve attached a screenshot of the exact error. I don’t see any option to “clear the mail cache” and my drive has over 1.5TB space.

Does anyone know how to fix this? Otherwise the game works 100% (even better than on Windows honestly).

Thanks!!

No one told me you had to press ESC during game play, then click “Reset Settings”, THEN you can ckear various caches.

I cleared the mail cache and it worked!

Thanks!
