Can't load Model D VST3 (which works in pedalboard)

[turian]

I'm trying to load the Moog Model D VST3

import dawdreamer as daw
engine = daw.RenderEngine(48000, 1024)
synth = engine.make_plugin_processor("modeld", "/Library/Audio/Plug-Ins/VST3/Model D.vst3")

gives

error: attempt to map invalid URI `/Library/Audio/Plug-Ins/VST3/Model D.vst3'

synth.load_preset

returns True and the get_parameters_description() appears to have the correct names, but doesn't load the values. And the renders are empty.
