if you close the game window, reopen it, and go to the "warnings" page, what version does it say the game is?
Cool! So the error is coming from somewhere inside the Sugarcube framework, and not the actual game code I wrote, which means it's something that I have really no power to fix. ;A; There's not much help from what I researched, but a possible lead is that you have some sort of browser extension/pop-up blocker that might be interfering? So my suggestion would be to check what things you have running in the browser, or try another browser (I just tested the game in Firefox and it seems like a good alternative). Sorry I can't help any more than that! 😭😭💖
