Camel Plugins black screen in Cubase 11

Hi

I am migrating to a new MacBook Pro and to Cubase 11 from 10.

Nearly all my plugins are working now but for some reason all the Camel plugins show up with a black screen, they work but there is no GUI. This doesn’t happen in version 10 on the new machine, where they work fine.

This is especially difficult because the developer no longer updates these plugins.

Can Steinberg please help with version 12?

Thanks
