Not able to start deployed process from VBCS application

Content

Hi Experts,

Create a PCS application(ReimProcess) and activated it on the server.

Developed a VBCS application and registered the above process and when I run the VBCS app in preview mode the PCS application is getting called successfully.

From the application setting, I have changed the Player Target Server to Default Target Server and staged the application. When trying to kick off the PCS application, getting "Internal Server Error"

When I click on the registered deployed process, I see the process in oracleinternalpcsplayer. When I click on three dots, I don't see the process which I have registered in VBCS application. See the attached screenshot.
