Rotating the iPhone on sign-in popup guarantees a crash

Rotating the iPhone while on sign-in (Microsoft Live Login Menu) popup (reproducing MCPE-174398) now guarantees crash some time after rotating.

Steps to reproduce:

1. With Minecraft Preview open and Microsoft Account signed out, click "Sign in"
2. With the XBOX sign-in popup open, rotate your device

Expected result: At worst, when the game (app) was rotated, the game still would not crash.

Actual result: game (app) rotates and guarantees a game crash after some time, however the game won't crash until the phone's rotated

Note: This bug can't be reproduced on Apple iPad, and can only be reproduced on Apple iPhone. However for relating bug with pink screen on iOS (and iPadOS), please check MCPE-185373.
