Wavelab Pro 10 crashes with Soundtoys

I’ve been having trouble with Soundtoys plugins and Wavelab Pro 10.0.4 on mac osx 10.15.7

I get the error “Error, bad A0 coef”. I press ok and it changes to “Error, bad A1 coef”. Press ok and it’s “Error, bad B1 coef”. etc, etc… I have to force quit Wavelab. It happens the same every time with some Soundtoys plugins: I load the plugin, press play, all is well. I press stop and then play again and I get the error.

The soundtoys plugins are all up to date.

What’s the issue here?

I have the same issue here in Cubase 12.0.60 but only when I close/quit Cubase and I have no Idea what plugin is it.
If I open the project is all good, so I don’t understand but it works for now so no complains but it will be nice if it doesn’t do it.
I’ll try to find the plugin that is causing the error.

Soundtoys plugins. They don’t list WaveLab as a supported host for their plugins, and likely have done ZERO testing of their plugins in WaveLab. Maybe you can ask them to change that.
