Chat and command block input freezes or crashes the game

When I write something in chat or execute a input in command block, the whole game freezes or crashes. Its annoying and sometimes it makes me think of quitting bc its soo laggy too. I hope Mojang will fix these issues.

Steps to reproduce:-

1) Get a android or iOS MCPE but not a PC bedrock one

2)Load into a new or existing world

3) Open chat and start typing or try to execute a command in command block

4)There will be delay and on lower end devices it just freezes or crashed

Note :- This happens only in MCPE or mobile MC
