Does anyone recognize the thing that is happening in the screenshot and does anyone has a solution ?
When asking questions then you should always supply such basic information such as type of computer and exact version of OS , and the MacOS and Apple Silicon from your profile simply is not accurate enough (and do not expect people in general to check your profile for info) , Mac OS version ? M? , version of Native Access used ?
Is what is described happening with Kontakt as stand-alone or only in a DAW ? , if so please specify exact version of DAW
Also , please check that all N.I. apps including NTKDaemon have full disk access ! :
