Debian 10 - Failed to Display

Argos newbie here. I've got an install of argos3 running in a Debian 10 environment. "argos3 -q all" returns the loaded librarys and a list of actuators, sensors, etc. I built everything from source.

When I run the diffusion test experiment, it's failing here:

qt.qpa.screen: QXcbConnection: Could not connect to display
Could not connect to any X display.

This is a remote system (EC2 instance) so I've added a desktop and am connecting with VNC, which included some connection to X. I'm not versed in X windows. Can anyone suggest where I might be going wrong? Or suggest a path to pursue for debugging and fixing my environment?
