Hi ! Did you place the game folder in your documents folder ? If so have you tried moving your game folder elsewhere ?
Yes, I've tried it from User\Documents\My Games\Documentia, User\Documents\Documentia, and Desktop\Documentia, with no luck. I can confirm that the game at least lasted long enough to write data into AppData, if that helps! That actually might be part of the problem; It's writing to an output_log.txt at User\AppData\LocalLow\Pandanym\Documentia. When I last checked it, it was 80.4 MB, and has only been growing larger. It looks like a memory leak. I've pasted the important stuff here: https://pastebin.com/1sgujQ65
Not sure what could be causing this when others are having no problems, but it seems to be an issue on Unity's end instead of yours. This looks like an interesting game, too, which is kind of disappointing, but I'll figure something out! Sorry for the trouble!
