Ventura 13.3.1 here, using Logic Pro X 10.7.7.

Nectar 3 appears to work fine. Individual controls are available, and the Vocal Assistant runs to completion.

Neutron 3, less so.

Individual controls are available, but Mix Assistant / Track Enhance stalls while “Waiting for you to play audio…” and Mix Assistant / Balance gives the popup error “Some files required by Mix Assistant were not able to be found. Please reinstall in order to use this feature.” At one point, while in Mix Assistant, Logic crashed completely.
