Puppet operates using a master-agent architecture. On Unix/Linux systems, Puppet agents run as daemons. On Windows, Puppet requires additional helper processes to manage sessions, user contexts, and permissions—this is where psminitsessionexe enters the picture.
When troubleshooting PSMInitSession.exe errors in a CyberArk environment, you're likely hitting one of the most common roadblocks in a Privileged Session Manager (PSM) deployment. This executable is the heartbeat of a session; it's responsible for taking the connection information from the PVWA and launching the second connection to your target.
A legitimate PSM process connects to:
: PSMInitSession.exe validates session parameters, locks down the container environment, notifies the broader PSM service architecture that the connection has successfully begun, and spawns the target connector script. Configuration Mechanisms and Storage Paths

Have you checked the Windows Event Viewer for AppLocker blocks?
Temporarily set AppLocker to "Audit Only" to see if the session connects.
