Plugins show empty interaction window, and manager shows multiple instances of one plugin.

Issue type

UI bug (incorrect info or interface appearance)

Description with steps to reproduce

For a multitude of plugins I get an empty interaction window. Previously (before update from an earlier version 4) I got a window with options. (see attached first two pics) and the plugin worked fine.
Also, in plugin management panel I see 4 instances of chordIdentifierPopJazz_0 (see attached pic 3)
And, when I enable one instance of chordIdentifierPopJazz_0, another instance is also enabled and I get 2 menu items of which one greyed out. (see attached pic 4)
I did drop a copy of chordIdentifierPopJazz_0 in the plugins directory in an attempt to reinstall it - It was not in the directory before i did this, and not in any subdir. I now still see only one copy in this directory, while I have 4 instances in the plugin manager. Note: when I had zero chordIdentifierPopJazz_0.qml files in the plugin directory I still saw 2 instances of the plugin in the manager - and after enabling one the other also gets enabled but greyed out in the menu.

Currently running OS: Windows 11 Version 2009 or later, Arch.: x86_64, MuseScore Studio version (64-bit): 4.4.4-243461245, revision: 2232670

Test score has Fm Db Ab and Eb chords. Obviously no chord names appear: there's no okay button to click on.

Empty interaction windows:

• ChordIdentifierPopJazz0
• ChordIdentifierSp3_22
• scoresToJSON (dont see it in the library anymore, cannot verify compatibility)
• ToDo List

Empty buttons in interaction windows (button could say "OK" "Cancel" "something else")

• Tuning
• WalkingBass

No action noticeable:

• Score Duration
• Add Metronome Part
• RepairAssistant

Working as expected by me are:

• ColorNotes
• NoteNames

Wrong screenshots added: expandChordSymbols is incompatible with ms4. However the screen looks the same as for the compatible plugins like ChordIdentifierPopJazz0

AFAIK that's an issue with those plugin not having been adjusted to MuseScore 4.4's changed plugin API

[fzoet69]

Thank you Joachim In that case it might be helping to show the compatibility with 4.4 in the plugin library. Library now shows compatible with 4.x, and as I understand now compatibility is broken after 4.3. This may also help developers to keep track of their plugin compatibility.

Yes. That's been requested in the forums on musescore.org several times already.
Might be a task for @shoogle

Just confirmed that the plugins work with the latest 4.3 portable version. Downloadable here, under "assets": https://github.com/musescore/MuseScore/releases/tag/v4.3.2 Unfortunately scores that were saved in 4.4 are also not readable by 4.3. That could be solved by exporting as xml from 4.4 and then importing again in 4.3. This way plugins can be used until they are updated for version 4.4. Seems that 4.4 has a big impact on compatibility. A notification before upgrading would be appreciated by many, I think. Op wo 1 jan 2025 17:12 schreef Joachim Schmitz ***@***.***>:
