[Bug]: Plugin causes Jellyfin to crash when scanning series

Describe the bug

When scanning libraries the OnWatchedStatusChange is fired when scanning my normal Series library which causes this line to crash the Jellyfin server:

itemYTId = Utils.GetVideoNameFromPath(eventArgs.Item.Path);

I have specifically disabled the TubeArchvist plugin for the Series library but the issue persists unless I disable the plugin.

Steps To Reproduce

• Install TubeArchvist JF plugin version 1.3.2 and start a full library scan.
• When it gets to scanning Series it restarts the Jellyfin server because of the crash.
• Server starts back up, restarts scan and crashes again and this repeats every few minutes indefinitely

Expected behavior

• Install TubeArchvist JF plugin version 1.3.2 and start a full library scan and have the scan complete successfully for all libraries

Relevant Jellyfin log output

System.ArgumentNullException: Value cannot be null. (Parameter 'source')
   at System.Linq.ThrowHelper.ThrowArgumentNullException(ExceptionArgument argument)
   at System.Linq.Enumerable.Count[TSource](IEnumerable`1 source, Func`2 predicate)

   at Jellyfin.Plugin.TubeArchivistMetadata.Utilities.Utils.GetVideoNameFromPath(String path)
   at Jellyfin.Plugin.TubeArchivistMetadata.Plugin.OnWatchedStatusChange(Object sender, UserDataSaveEventArgs eventArgs)

Anything else?

I've got a fork with a workaround here that I have been testing that I will open a PR for soon once I have made a branch for the specific fix.

Are you sure you don't have enabled TubeArchivist plugin on the wrong collections? I can't reproduce the issue you face

[wolffshots]

Yeah I'm 100% sure I don't have it enabled on my normal Series collection and it's not an option on any other collections. Any other ideas what could be causing this?

It seems to happen every time I run a scan on my Series collection but the other seem to work fine (including the TA collection)
