Per the title, absolutely no app will launch through Bluestacks. I even did a fresh install, and it's still not working. I can't open Google Play, I can't open my Pathbuilder app (which is what I was really after) and I have no clue what to try next. (I think it might have deleted all the data from my Pathbuilder app anyway, though, which would just double-suck.) Before updating my bluestacks I could install any app from Google Play Store and I could even install third party apps like loklok on my laptop (https://loklok.onl/pc/) easily
