Problems with DSP56300 Osirus VST3 plugins (and others)

Hi, first time poster here.
Since the latest update, I’m having quite a bit of trouble running (several) VST3 Synths, espcially the DSP56300 Osirus.
Sometimes it just don’t reacts to pressed keys anymore. After Closing the window, using as active instrument it reacts again, after opening the window again it stops reactting again, and then: complete crash.
Happened a few times like that.

Same with other VST3s. I’ve been havin’ troubles like that a lot during the last few days.

Any infos on/ ideas to that that?


Is this on macOS, Windows or Linux?
