Cubase 11 crash when instantiating IK Muktimedia Lurssen Mastering Console

I hope this is the place to submit problems for technical support?

Having a problem with IK Multimedia’s Lurssen Mastering Console (vst 3,6,0) causing Cubase 11 to crash. This occurs when a control on the plugin is touched, after successfully opening the plugin.
Using Cubase v11.0.10.321 - Macbook Pro running Big Sur 11.2.2 - Lursenn MC v1.1 (vst 3.6.0)

This also occurs with Outputs Thermal plugin v1.0.2.0 (VST 3.6.12) except the plugin doesn’t open - just crashes Cubase.

It occurs with new empty projects and existing projects.

Both of these plugins work fine with Ableton 10 and Reason 11.

Crash logs for both are attached.

Please help.

Hi and welcome on the forum,

The crash is in the plug-in’s framework, IK Multimedia plug-ins are using: JUCE.

I would inform IK Multimedia.

Hi Martin
Thanks for your response - sorry mine has taken so long, but I’ve been sick with a virus that seems to be going around at the moment.
I did inform IK as you suggested and the problem has been fixed in a maintenance update.
