Quick Text Chat Issue | Game stops responding

Please fix the Quick text chat issue ASAP, 

When ever I press "enter" button to access the text chat, In back the whole game is running but I cannot click anything, I AM STUCK.

Even after pressing "h" which is to switch the modes of chat or pressing "esc" and "~" Buttons, It's no use. Nothing responds, Expect the chat of course. I am able to use 'TAB' to switch between 'Squad' and 'All' mode , And the mouse clicking also works but on the Chat window only. And the worst part I am not even able to type anything !!

It's like there's a whole another invisible layer for the chat which come in front of everything and the game stops taking the input from the keyboard for the game which is running in the background.

And due to this I am not able communicate with my teammates effectively.

It's so frustrating that I have to completely exit the game (Sometimes mid match) and restart the whole thing again. 

I tried my best to explain the issue in detail so that it would help the Dev team to understand the problem. So for the Second time I request please Fix this issue ASAP.
