“Changes in the Windows April 2019 update for Client Server Runtime Subsystem (CSRSS) introduced a potential deadlock with ENS,” McAfee says. “McAfee is investigating this issue and will resolve it in a future update. A Proof of Concept (POC) build to test a fix is currently available. Escalate a Service Request to Technical Support to obtain the POC.”Via: Softpedia
The workaround, according to the McAfee, is to “disable any access protection rule that protects a service.”
