KB5025229 Breaks Secure MQTT

Has anyone experienced an issue with Secure MQTT after updating the WMS host server with KB5025229??
Shortly after the patch is applied I see all traffic being redirected to the unsecure port (1883). I've verified that the traffic is traversing the firewall, but being tore down by the server after that. I don't see anything that sticks out about that update except a potential fix to MySQL. However the timing in my case is uncanny as the failures begin only 6 minutes after the patch is applied.

Go to a command prompt, netstat -ano |more  Find the port for secure MQTT? 

1) Is it present?

2) Fond the PID for that port listener and compare it to the process in Task Manager, what is it?

No Events found!
