This has occurred so far using ES31 with Launch On to Android. It didn't occur with ES2 or Vulkan.
I've been able to Launch on to HTML5 on Firefox with no issues.
This was tested on a Pixel 2, 8.1.0 (Adreno 540)
RESULT: Crash missing global shader cache on (4) but not (6)
There's no existing public thread on this issue, so head over toAnswerHub just mention UE-57505 in the post.
