The plugin is copied to "C:\Program Files\MuseScore 3\plugins\" but doesn't appear in the Plug-In-Manager. I use MuseScore 3.6 on Windows 10 Pro (20H2) 64 Bit

Confirmed. When I load it into the Plugin Editor and try to run it the console shows:

Running…
Creating component failed
line 219: Expected token ;'
line 220: Expected token;'

So the plugin has syntax errors. the code:

                        getOutput: function(format) {
                              let tDL = textdeco(this.pitch, format, true)
                              let tDN = textdeco(this.pitch, format, false)
                              switch(format) {
 

Adding the 'missing' ; doesn't fix this though, so there got to be more to it.

Apparently the cause is a too old version ot Qt (5.9.x), in a self-built one using Qt 5.15.2 the plugin just works. So it seems those let lines are a feature of the newer ECMA 6 version of JavaScript that newer Qt versions (starting with Qt 5.12) supports.

Changing the code to

                        getOutput: function(format) {
                              const tDL = textdeco(this.pitch, format, true)
                              const tDN = textdeco(this.pitch, format, false)
                              switch(format) {
 

or

                        getOutput: function(format) {
                              var tDL = textdeco(this.pitch, format, true)
                              var tDN = textdeco(this.pitch, format, false)
                              switch(format) {
 

i.e. replacing let with const or var fixes this, so the plugin would work with all released versions of MuseScore 3.

Status active ⇒ fixed

But then again the plugin you downloaded from that page was the wrong one, ExportNumbersMNLetters instead of ExportStaffMP3s, corrected now. That one does load properly.

A new issue against ExportNumbersMNLetters might be needed to get that code change in

Ääähm...
Now it's getting weird!
After your last answer I downloaded the new file you mentioned.
I loaded a three part choir score.
Hooray!!! The plugin is shown in the plugin manager. The plugin starts, I select a folder to save, everything is fine, the plugin closes as it should and I "go" to the folder: EMPTY!!!
oops! Okay, I'm a little clumsy sometimes. So again from the beginning: Now I chose Desktop as the folder, but alas same result: Nothing..
What now?

Not sure there is a preferred method, but check e.g. my Batch Export plugin or @jeetee's Tempo Changes one, both do work in Light and Dark mode as far as I can tell, but apparently neither do any special coding for that.
