Maybe try saving a game, don't even really have to go very far into the game, just after the intro should work. See if it makes another folder in Quest Nav folder.
There's bugs in every release, but if you're after something less buggy. Can try my project if you haven't already, link in signature. Cheat version has content from the 0.23 release but the cheats themselves I haven't gone through and updated them yet. Still on the 0.22 release for those, maybe if I stop procrastinating this weekend and update them...
