When I launch this game, I just get a gray screen with floating leaves only. I tried to solve this issue by shortening game folder names, reinstalling unity, using compatiblity settings etc- but the problem unfortunately persists. The WebGL version funnily enough, actually works without any noticable problems
oh, im assuming you already used the unity crashed handler then,if you didnt tho then go under and there should be an application called unity crash handler.Basically this:
(and yes the red circle is perfect)

Tho if thats not the problem.Then you could try redownloading the game,tho as the last option you probably already did that.So you only option is probably reporting this problem developer(probably)
basically this:https://www.theforestoflove.com/bugs
The crash handler doesn't solve bugs, it dumps your crashed game and sends the info to the dev. I also did send a bug report too, just writing this down here to make them notice the bug more and for players whom have experienced the bug to write some solutions or also say that they have experienced it idk
