AU plugins freeze in MPC 2, inside Logic Pro

Hi All

When I open a plugin, like Fabfilter Pro C2 using MPC 2 inside Logic Pro, I get a black plugin screen saying, 'click to view plugin' and it freezes, nothing happens when I click the message. I'm unable to get rid of the black plugin window, unless I close and re-open Logic


This happens with lots of plugins.

OS Sequoia 15.3.2
Logic Pro 11.1.2
Evo 16
192 Ram
Mac Studio M2 Ultra

Is this a bug?

Thanks
