Maybe it's happening for you because your Defender services were stopped by Defender Control prior to installing Kaspersky, not automatically after installing Kaspersky. Also, Defender Control is not updated anymore so it doesn't know about the new Defender Core Service. So that could also result in incompatibility. If none of this is correct, then it could be a bug from Kaspersky's side. Looking at ESET, their Security Center integration module was last updated in August 2023, so the integration method hasn't changed in Windows for a while.
