Crashes on MAC OS (12.2.1)

I have been using em Client (currently 9.0.1360) for 4 weeks and am thrilled. But since yesterday nothing works anymore!
I wanted to move some mails to a local folder. First the window "This process may take a moment…) appeared. Then em client crashed.

Unfortunately, restarting the programme was also unsuccessful. The programme crashed again shortly after starting.

Restarting the computer also without success.

I get em client to start offline, but as soon as I get the computer back online, the programme crashes.

What can I do, finally a mail programme that inspires me and now this…?

As the latest V9.0.1360 is still Beta 3, I would send an email to advise the issue (via your webmail) to and include your Mac OS version.

I could have thought of that myself

Till you hear back from testing, you could also try reinstalling eM Client for Mac V9.0.1360 Beta 3 via first dragging the eM Client folder to the bin and then try reinstall the same Mac version from the ver history page.

Alt if you made a recent time machine you could also try rollback and see if it then works ok.
