It happens when I open the game
In that case, something definitely happened to one of the files in the game (not your save file, hopefully!), so follow the instructions I said above to keep your save file intact as you reinstall the game.
Before you reinstall, I'd like to get your Last Error.txt file. It's located in: Tailor Tales/www. There should be a text file in there called Last Error. If you could open it up and copy its contents in your post, that'd be great!
Here it is,thank you
NAME: TypeError

Okay, I'll need to give you a file that you can replace in the game, is it possible for you to get on Tailor Tales' Discord and say something in the tech-support channel? Then I can give you that file and see if it works.
