Game Client Crash When Uploading packs to a realm.

Hello! i want to report a issue with mcbe realms. basically if you attempt to upload a texture pack(one which changes guis), and a behavior pack(mainly those including functions and structures) to realms the game will lock up then crash. could this possibly be investigated?

steps to reproduce
1. have a realm available
2. install the attached resource
3. apply the uploaded packs to a realm

Observed Results
from my observation(mainly on the device the crash occurs on)
the issue seems to be caused by certain behavior packs with a certain manifest.json setup

Expected Results
you should receive a crash on your device due to uploading the pack, this issue seems to affect windows 10 only.
