FreeFileSync starting problems under MacOS Big Sur

[uwenet]

Just updated my iMac to the newest version of BigSur.
Even after reinstall from FreeFileSync 11.5 Donation Edition it won't start.
Errormessage: The Programm FreeFileSync.app is not open any more

But I can start it from terminal without error?
(I used it with cron, that's why I tried this)

Thanks
Uwe

Is this a permanent error, even after restart?

After the restart I can start your program again!

I think there was still a process running. Perhaps because of the message from the first start that I have to set the Preferences (Security).

Thank you!
