Halion sonic 7 super slow loading instruments

Hi there,
Halion sonic 7 super slow with loading instruments. It just frezes a long time. In the end I get some sounds, but it is really unusable like this.
I have an M2 Macbook air, seperate Samsung T7’s for samples and a seperate one for recorded audio. A great RME interface. I’m on Sonoma 14.7.1 with the latest Cubase pro 13.0.50
All other vst’s work instantly. Full Sampletank 4, Ivory II, Kontakt etc…
I read some comments on this, but that didn’t really help me. Has anyone found a sollution?
Thanks,
