Hey Man!
I'm having a similar problem. Within a week I started to develop a project. I was testing on the android phone, LG K7, no problem. From yesterday my tests started to present a problem with black screen. It happens the following. The game starts but soon after a few seconds all the splits disappear, but the game continues to run because some elements like testo box and buttons that are not splits continue to be displayed. It looks like it's some problem in start of layout. Time works perfectly, time happens black screen.
It's my first project with Construc, I do not know what to do.
Just the problem in tests on the cell phone. Android Debug Apk. No Construct works perfectly.
