This problem appears somewhat randomly, it doesn't happen on a specific project, sometimes it does, but sometimes it doesn't.
Recently, I often find that I cannot download the exported HTML 5 compressed package, and Chrome always blocks it.
After checking for a long time, I found that it turned out to be a Microsoft problem. It identifies c3runtime.js as a dangerous file
I don't know if I'm the only one having this problem, but of course the easiest thing I could do would be to fuck Microsoft Security and turn it off permanently.
