Yes I have tried deleting the game and re downloading it as well as trying to copy the files from the original zip over the folder I created and it still does not seem to fix the issue. I have tried several times.
I have a hypothesis for the cause of this problem. I think it may be the use of special Portuguese characters in the name of some assets.
