Sorry to bother you, could you copy what the error says exactly? I've been trying new saves in different browsers and such, can't seem to replicate your issue thus far
I can confirm that's never been a file present in my project haha. I suspect something strange is going on related to how web deployments manage saves, probably a game ID issue but it's beyond me... your most recent project is calling files used in mine, for example. Maybe try playing in incognito mode, that seems to avoid file conflicts on my end
