digiKam keeps running in background after quitting the app (v8.6.0 on Debian GNU/Linux 13)

Hi :wave: Did anybody struggle with the case when digiKam keeps running in background after quitting the app and consuming memory on Debian 13?

I tried to find an active option in “Miscellaneous Settings” which can lead to it but without any luck.

digiKam version is 8.6.0 and it is installed from the Debian repo.
