BR : impossible to "load" the VST MUX Modular PlugIn in Waveform on mac

[Lutin mutin]

Hi TSC Team !

Reporting that Waveform 8.1.2 here on Mac don't accept to "load" the VST MUX Modular plugin (v7.4.11) - Mac version, from MULAB.
Waveform don't crash, but blocks - "freeze" (coloured spinning circle indefinitely), until I force it to close through the dedicated finder window.

Hope you will find a way to fix it,
Best regards.
