If you want to try editing the save data directly, you’d be searching for a localStorage file in there. If you search for the string “exo_game” you’ll find some JSON with a “position” key. I suspect it has an infinite number in it. The programmatic fix I’d add in a hotfix would set them to sane default values like (0, 0, 0) for your coordinates and (1, 0, 0, 0) for your quaternion. You can try that manually if that makes any sense, but do make a backup first.
