The gnome-control-center crash seems to be a side-effect and a bug there, but just for the record (1:3.30.2-2):

(gdb) list
318	  gtk_widget_show (prefs->button_calib_upload);
319	  ret = cc_color_calibrate_setup (prefs->calibrate,
320	                                  &error);
321	  if (!ret)
322	    {
323	      g_warning ("failed to setup calibrate: %s", error->message);
324	      return;
325	    }
326	
327	  /* actually start the calibration */

Same or similar issue with Fedora 32. When trying to calibrate my monitor using Gnome Control Center, I randomly get one of the following errors:

• (gnome-control-center:10212): color-cc-panel-WARNING **: 13:59:58.638: failed to start calibrate: GDBus.Error:org.freedesktop.ColorHelper.FailedToFindSensor: failed to lock: usb:01:00:02: Invalid read: retval=0x0a [Invalid value] cmd=0x35 [get-remote-hash] (expected 0x35 [get-remote-hash]) len=64 (expected 22 or 64)

• (gnome-control-center:11088): color-cc-panel-WARNING **: 14:05:18.128: failed to start calibrate: GDBus.Error:org.freedesktop.ColorHelper.FailedToFindSensor: failed to lock: Failed to find device 0001:000a

Everything works fine with DisplayCal.
