Here the same.
I am at mailbox.org. IMAP works, Carddav and Caldav not.
Both are possible in Thunderbird.

Upgraded on Windows 11 too?
IMAP woks.

Yes, upgraded to Windows 11 Pro.

Same issue - after updating my computer to Windows 11, emclient no longer synchronise caldav or carddav.

For those using Windows 11, please update to today’s service release available in the Release History.

Thanks. Now it works.
