I recently migrated a client application to PB 2019 R2.  When I run the new exe for the application it starts, opens, connects to the database and then suddenly closes with no error message.  This happens on a Windows 10 machine.  It runs fine from the PB IDE.  It also runs fine from a different VDI machine that doesn't have Symantec and other services running.

The existing application was built with PB12 and is installed on each user workstation via Software Center.  That application works normally after installation.

What types of windows and/or network services and processes could be causing this application to suddenly close?  I debugged the issue and it halts when it tries to open a non-visible window that has about 5 or 6 datawindows which are instantiated and then used as datastores.  Again, no error it just halts at that line of code.  This happens after the database connection is made and after other logic is executed.

I played around with the Security tab in the project object and tried using an embedded and external manifest but that had no effect.  Could it be that this new exe of the application is being blocked by DLP software?  If so, how could I determine that?  Things are locked down on this machine so I can't disable much due to lack of permissions.

Thanks, Tom
