Lightroom CC not seeing plugins

[#1]

Windows 10 and Lightroom Classic 10.1.

File - Plug-in Manager shows Adobe standard plugins (that I don't want) and Teekesselchen that I do want to sort duplicates.  I had this plugin last November and all worked well - very well.  However, my PC collapsed, so I now have a new PC (after being away a couple of months) and reinstalled LR and Teekesselchen.

Plug-in manager shows all these plug-ins enabled and running.  But

File - Plug-in Extras only shows LogiOptions (greyed with a version number) and that is all.

I cannot find Plug-ins elsewhere.  So I cannot run Teekesselchen.

Also, Location - Store Presets with this Catalog is unchecked.  (A solution to other Plug-ins not appearing.)

Can anyone help with this?

Two things,

First, disable the LogiOptions Plugin, it is very buggy. You might want to get rid of it.

Second thing in next reply

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

Note that not all plugins work thru /File/Plugin Extras/

For example, Some are accessed via /Edit In/

So, on my WINDOWS 10 with LrC v10.1, same problem with Teekesselchen.

Now, at v10.0 some third party plugins started failing, and I needed to get a new post v10.0 copy. Unfortunately v1.8.0.1 has not been updated as far as I see.

Yikes per Teekesselchen web page, this is 7 years old

...and also Library > Plug-in Extras.
