We've had one arcade have 5 installations on 5 identical PC's and one of them had this issue. All I can think of is there's a glitch with the "fall off the plank" setting. Removing the game and re-installing may not remove the saved settings.
To force a reset of all your settings, open regedit and all the keys in Computer\HKEY_CURRENT_USER\Software\Toast VR\Richie's Plank Experience
Sorry you've had this problem. It's extremely rare and we've yet been able to replicate it.
Please let us know if this helps!
