Synology "Failed to start SABnzbd"

Hey all.

Synology DS1817+ with DSM 7.1.1-42962 Update 5, SABnzbd version 3.7.2-60 installed with Python 3.11 in support as expected. Every repair, uninstall, reinstal etc has the same issue, "Failed to start SABnzbd"

It used to work fine (it's been a while) but I think DSM 5.x was the last time it has officially "worked". I don't believe anything has changed systematically except for updating DSM and python versions in support.

I've looked for info to try to evaluate how to troubleshoot, but the info is sparse (or my search skills suck).

Any pointers?

You should remove the package with all content and then reinstall.
Could be that some leftover sabnzbd.ini setting that causes a problem.

I don't know if this helps anyone, but I had a similar issue where my long-running SABnzbd crashed and failed to restart so I decided to solve it.

I copied all SABnzbd files, completely wiped the installation and then tried to copy back my configuration and old database.
It turns out that it was the old database that for some reason got corrupted.
If I (re)moved the files /var/packages/sabnzbd/var/admin/history1.db & rss_data.sab and replaced them with files from a fresh install, SABnzbd once again runs as it should.
