I have the same issue, I restarted the app and unrar binary and par2 binary are now found, but I still get SABYenc module... NOT found! Expecting v4.0.0 -
https://sabnzbd.org/sabyenc error.
I have version sabyenc-3.3.6 installed, cannot install a version 4.0.0 at all:
root@NAS1:/volume1/.@root # pip install sabyenc==4.0.0

When starting sabnzb I can see it detects the version.
