Sonarr/SABnzbd+ no longer post-processing TV episodes correctly

Sonarr version 3.0.10.1567:
Mono version 6.12.0.182:
OS: macOS 12.7.6

Description of issue:

On or about 8/1/2024, my former means of post-processing tv via my old sickbeard script in SABnzbd+ disappeared. The post-processing script folder is empty and my time machine backups going back 2-years don’t have anything in the suggesting it was there even back then, even though it was working fine.

I have Sonarr setup with preferred naming conventions of shows, etc. Haven’t touched my Sonarr settings since I replaced sickbeard with Sonarr many years ago. My shows folder structure, prior to the 8/1/24 changes, look like this:

Volume TV

[ShowName]

Season 1

[ShowName] - S01E01.file

Since post-processing started failing, everything from SABnzbd+ saves the downloads as individual files/folders in the TV directory like:

Volume TV

Show.Name.S11E30.720p.HEVC.x265-Tag

Show.Name.S11E30.720p.HEVC.x265-Tag.file [OR]
;kdjsaf09u43opijva09j43q0inq3;lk.file

Sonarr Media Management > Episode Naming, Folders, Importing, etc. is the same as its always been. SABnzbd+ had the tv folder/category set to “auto-post-process-tv.sh” from the old “my-sickbeard-install” folder that still exists, but is now empty.

Please help! Also, given the months of disorganization, once this is fixed, how do I complete manual post processing of all these items into their correct places using Sonarr or SAB? Haven’t had any reason to touch this in years and I feel like I’m a noob starting from scratch sigh
