"Calibration failed!" (unable to start monitor display calibration when argyllcms is not installed)

In Fedora 33 Silverblue with gnome-color-manager-3.36.0-3.fc33.x86_64, when I attempt to calibrate a screen with a colorimeter (x-rite eye-one display 2 or an old ColorVision, Inc. Spyder 2), I get the following:

"Calibration failed!" "An internal error occurred that could not be recovered. You can remove the calibration device."

Attempting to run the calibration a second time causes GNOME Settings to crash (after running through the color manager prompts about native/D65, etc.).

I don't see much in system logs except:

dmesg:

But that's probably from the second time I ran it, when GNOME Settings crashed.
