Mixer does not show Yamaha MOXF VST3

I would like to use my Yamaha MOXF for audio playback on my Mac. When I click on my track in the Mixer, it shows in the VST3 popup menu no Yamaha.

Environment: Mac mini, MacOS15
VST3 folder: /Library/Audio/Plug-Ins/VST3/Yamaha/MOXF6_MOXF8.vst
MuseScore Preferences Directory: included /Library/Audio/Plug-Ins/VST3/Yamaha

The file known_audio_plugins shows an error code for Yamaha
[
{
"enabled": true,
"meta": {
"attributes": {
"categories": "Instrument|Synth"
},
"hasNativeEditorSupport": true,
"id": "LABS",
"type": "VstPlugin",
"vendor": "Spitfire Audio"
},
"path": "\/Library\/Audio\/Plug-Ins\/VST3\/LABS.vst3"
},

},
"path": "\/Library\/Audio\/Plug-Ins\/VST3\/Yamaha\/MOXF6_MOXF8.vst3"
}
]

The LABS plugin can be selected but the control window is white.

Does the Yamaha MOXF works anyway with Musescore??
