SeaDrive Sync Error without showing an Error in the app?

Hi,
I’m in MacOS 14.7, seadrive 3.0.11

I tried to resync the accounts but failed.
A error message in pop-up says :
Failed to connect to background process, please try again later.

I checked the seadrive-gui.log, there is a looooooot of error messages … see in attachment

Thank for your help.
