I have the same problem with this version r157, my statistics on Google Play developer console showed many Crashes and ANR.
I think I'll have to go back to the previous version.
In this version r137 my game gets the black screen, but the sounds of the game continue working normally. This only happens with the APK. It works fine in Desktop and Mobile preview.
The APKs with "C3 Runtime" do not work in some Mobile, the following message appears:
"Browser not supported"
"This content is not supported in this browser. Try installing any available software updates, or try using a different browser."
But with "C2 Runtime" it works.
