Failed to take screenshot via portal: Screenshot failed

[deafboy]

What Happened?

The initial window opens, although it has sharp corners instead of standard rounded corners. The screenshot type selection works, and correctly attempts to capture desktop / window / area as requested. After clicking the "Take Screenshot" button the screen flashes briefly, and the app exits. Nothing is saved in the screenshot folder, nor the clipboard.

Flatseal shows X11 windowing system permission enabled and "Session Bus" talks to "org.gnome.Shell.Screenshot"
