HELP: Cafe Rouge black screen

[Ajedrez20]

Hello! A while ago I downloaded Café Rouge right here, but due to time issues I had not played this title, yesterday I unzipped it and ran it without problems, the game started without any problem, the bad thing started the next day when trying to play now out of nowhere the screen would not load staying black, I spent the whole morning trying to fix it and apparently there is an error in the json syntax I don't understand why if all I did was open the game see the first dialogs to check that everything was fine, uninstalled and installed the game several times deleting the files even but nothing that error does not go away, I would appreciate help.
