Windows Sandbox gives an error when attempting to start while PGP services are running:
Other similar errors with different error codes have been reported as well.
Windows 10
Windows 11
The File Share driver "PGPfsfd" seems to share components needed to start Windows Sandbox.
Currently, if you stop PGP Encryption Desktop with the "Exit PGP Services" option in the Lock Icon in the Windows Tray, and then attempt to start Sandbox, it will be successful. Testing shows that the services can then be started after Sandbox is fully running.
The PGP Development team is currently looking to rework the driver to potentially correct this and other issues. If you have interest in seeing this issue fixed, please open a support case through the Broadcom Support Portal.
