Edit:
Well, I'm an idiot xD
In my previous text I wrote that the game crashed for some unknown reasons. I finally fixed it and instead of just deleting this I'm writing about my idiocy xD
I haven't played this game since chapter 22, since there are now 24 I decided to update my game to the new version. The android version has this weird thing where you have to deinstall the old one because for whatever reason you can't just update it. It just says you can't. So you have to copy and save your savestates if you don't want to play the game again from beginning. I did exactly that. After downloading the new chapter and opening the game, I closed it again and wanted to put back the saves in the folder for the game.
Like with any other RenPy Game, the folder I put in the saves was the folder in the android section of the storage. Well, but after doing this, not only did my saves disappear, but the game just didn't want to open, even after installing it again and again. It got frustrating.
For some reason, I didn't realize that there was no game or any kind of other folder inside this folder, just a "traceback" txt document. And instead of seeing what's written in there I just ignored it and wrote a post here asking for help.
Now, after a few hours I tried it again only to fail again. But this time I finally looked at this txt document. It said something about a documentary being not empty and something something. The impotent part is, it was written there that the not so empty folder isn't in the "android" section but in the "document" section in the storage (Storage/android I think you know what I mean). If you go to documents, there is a folder with RenPy saves and in there is the game folder for MTWY. In there I still had, I can't tell why since i once installed it and it worked, but after trying to put the saves in the android part it didn't work, a saves folder. After deleting that, it finally worked. Even have my savestates.
The idiocy part by me is not reading the fucking txt decument, because it litterly was written there why the game didn't start.
I hope it's somewhat understandable what I mean, since English isn't my first language.
