Summary0009001: Ardour crashes when I try to add the ZynAddSubFX synth plugin to a MIDI track
DescriptionIt used to work fine in 6.9

For some reason when I start Ardour7 from the console, it doesn't crash in this scenario and works as expected.
Steps To ReproduceCreate a new MIDI track and replace the default synth with ZynAddSubFX - the application crashes.
TagsNo tags attached.

Further testing shows that the app crashes on trying to show the plugin GUI. When I don't try to show the GUI, the plugin itself works fine.

I am able to replicate this on Ardour 7.1.0 - as soon as the GUI opens, Ardour crashes. Short screencast here: https://watch.screencastify.com/v/as3AG13drqiNKP4x1Qhf in case that is helpful.

Happy to help with debugging and have attached a backtrace (thanks for the excellent docs, my first time so let me know if there's anything wrong/missing!)
