Slow loading and closing time plugins Cubase 15

Good day, it takes a long time for plugins to open and close in Cubase 15 pro, for example wavesfactory trackspacer and Tokyo dawn labs Arbiter.

I’ve got a Ryzen 7, 32 gb Ram on Windows 11 from 2025…Cubase 14 was very fast and smooth.

I’m going back to 14 pro for now, I’ve just opened the same project without the problems.
