When I launch my game from the UE4 project launcher (with “By the Book”, “Development” and Android_ETC1 set), the game runs on my Android tablet for about a second. I can see the map and the main character for a brief moment.
Then the game silently crashes with no error popup on the Android device. After looking at my logcat I see the following messages.

The main error appears to be “Assertion failed: ClearValue.ColorBinding == EClearBinding::EColorBound” What does this mean and what can I do to fix it?
My game is Blueprint-only, and I am using the official 4.9.1 binary, not source.
I should note that my game has run on this tablet before. So it’s not a problem of the tablet not being compatible with UE4 games.
