DK does not start with old db

Hi all!

- I installed DK 8.8 on my Debian 13,
- copied DK databases from another PC (Ubuntu 24)
- run Digikam, setting the db path to /home/antonio/Documenti/configurazioni/cfg Digikam/database/
- Digikam runs OK.
- Now starting DK from .desktop launcher has no effect.
- Delete all db
- Running DK, it suggest to delete Home/config/digikamrc
- digikamrc deleted

- restart DK, DK asked for initial settings but then DK does not start.
- Running from shell gives:
