Insert Plugins Not Responsive

I have a project from Cubase 11 Pro that had some plugins set to bypass. When I open the project in Cubase 12 Pro, the insert plugins are unresponsive. Clicking on them does not open them, & I cannot remove them or even turn off bypass. Any suggestions?

first of all you should state Mac or PC, because from what I understand there are a lot of changes going on within the MAC operating systems and their compatibility for VST

My bad - I’m on PC.

Resolved - The problem was between the seat & the keyboard :roll_eyes:

I had Freeze Audio Channel set on those tracks…
