ABC Import (plugin) not working since updating MuseScore

• Jun 6, 2024 - 21:12

I just updated to 4.3.1 and find my ABC Import plugin doesn't work.
Here is the process i've been using hereto:
-I acquire an ABC file from https://thesession.org/ - it comes down as a ".abc" file.
-I open this file using Notepad (Win11 pc).
-Select All & Copy.
-Open MuseScore
-Start a New Score (just General- treble clef)
-Go to Plugins then ABC Import
-This opens a window where you can Paste your ABC tune, or use an Open file button (I choose to paste).
-Then click Import.
-This creates an XML file
But when MuseScore tries to open the xml file it give error that its not a valid MusicXML file.
I can see that it's not going to work because the XML file is just 1kb.

When i open the XML file in Notepad it shows there was an internal server error.
