Hello, the title makes the problem quite obvious... But I'll go into further detail.
Recently, I've downloaded a few games (made with renpy) and before I could play them just fine. But for some very odd reason a week or two ago all of a sudden I couldn't open the applications at all!
This only happened with apps made with renpy and I'm confused on what happened. None of the files had been changed, nor has anything happened with my operating system (windows 10). I tried restarting and a couple other methods (like command prompts) thinking that's why I couldn't open it but the problem still persists! I've also tried un-installing and re-installing the games but that doesn't work either.
EDIT: After deleting the files AGAIN and re-downloading and unzipping them all I can finally play the games. I don't know why my PC is suddenly able to open them but I'm just glad I can finally enjoy my games.
