OVR SpaceCalibrator displaces me + my aligned VR trackers consistently into the air, even after reinstall

[rascheln]

I have asked this same question in the discord (which fills this textbox as a suggested first route) and received no response.

I consistently get displaced +4 meters vertically (and horizontally by about 2 meters) when using OVR SpaceCalibrator. My controllers and trackers align perfectly between quest and lighthouse tracking.

I have attempted a complete reinstall of steamVR (the one that involves clearing all the data files left behind after reinstall as well), and a reinstall of OVR SpaceCalibrator, but the issue persists. It's as if I'm using OVR Advanced Settings to playspace-move myself into the air, but the issue exists even without running OVR Advanced Settings. Attempts to playspace-fix using that program just gets auto-undone with approximately a 1/2 second refresh rate.

I wasn't displaced into the air before I had OVR Space Calibrator running. When it was running, the displacement into the air immediately occurred. So, when I'm playing steam VR games, in practice, from the quest pro, my character is basically floating in the sky with their controllers and trackers similarly displaced (including my camera view).

Any idea what's going on? When I uninstall OVR SpaceCalibrator, are there additional files left behind somewhere that I can clean up? registry entries? I'm really shooting in the dark at this point. Everyone I've talked to has never encountered this problem, but I seem to have narrowed down the problematic piece of software to OVR SpaceCalibrator, as this displacement only occurs with this program.

The big key here is: The calibration is perfect between quest pro and index. It's just that OVR SpaceCalibrator thinks that the correct quest pro playspace is located 4 meters in the sky compared to the index playspace. This displacement has been 100% consistent across steamVR and spaceCalibrator reinstalls. I have redefined both the index and quest pro chaperones/playspaces multiple times with no change to this behavior.

I'm running windows 11, with Vive trackers and a Meta Quest Pro.
