I have tried logging out and logging back in, but had no luck. Not familiar with the options though. I don't see anything relevant about the platform, as far as I can tell.Have you tried to logout from your IDE, and then log back in? And then make sure you have setup whatever is needed under FILE-PREFERENCES-PLATFORM SETTINGS -(whatever platform you're targeting), and another in GAME OPTIONS (the three dash icon) before building your export.
It was a known issue on YYG's end affecting some users (me included).Try to reinstall the IDE (do clean reinstall), read the article that I last sent. It seems the Runtime download process got corrupted.
