Problems in reinstalling Home Assistant on synology

Hi to everyone,
I just tryed to reinstall HomeAssistant on my synology NAS, after having messed up python.

I followed the same steps I did a year ago for the first installation as described here
https://www.home-assistant.io/docs/installation/synology/

But this time it doesn’t work.

When I start HA, I just see an empty home-assistant.log. I have no clues about what is wrong.

Can sameone give me an hint?

Thanks a lot.
