Peek360 Fails to Open

Recently, my two end-users are logging in to their computers, launching Articulate, then attempting to launch Peek.

Peek will launch and show as a "camera" icon in the system tray... When you hover over the Peek icon, it unceremoniously disappears.

I have tried the uninstall/re-install Peek.

I have checked the .Net 4.8

I have full uninstall reinstall of Articulate (freshly downloaded today).

None of these worked.  I'm at stand still.

Thoughts.
