Application always closes

So I have had this major issue for roughly 10 months where Minecraft closes randomly, no error messages, no warnings, nothing except the screen going dark gray, and Minecraft closing. I downloaded Minecraft from Google Play and I was wondering why it happens so much, and how to stop I from happening. Also a bug I have experienced is where I try to place a shulker box in my creative inventory, and the game stops, the game starts shaking violently, and I can't do anything but power off the chromebook. This glitch has cost me 2 of my favorite worlds, other times it just restarts. Sometimes Minecraft just closes out every 2-3 minutes, if i'm lucky, then 10 minutes and if I am extremely lucky then 20 minutes, MAX, then it just closes it out. I don't do anything to make it close to my knowledge. I have looked this problem on Google for many months and I get the same thing "Power off the computer" and when I do, then Minecraft refuses to open. When I click the Minecraft application, it gives me a small window saying "Starting Minecraft" An hour later and I get the same "Starting Minecraft" Message, and when it does open, I have to go through all of these previously explained bugs. Often times when Minecraft opens, I open a world and my mouse cursor doesn't move my POV. To fix this I always have to restart my Chromebook, which leads to the Crash, the non-cursor movement, and the "Opening Minecraft" problem. I really enjoy the game and the creativity this game implies, but it gets extremely frustrating when anyone of these problems happens. In a hour long session of playing, I am fixing these bugs or waiting for more than 20 minutes. I really just want help, or this to be fixed, because it seems each time you release a "Fixed bugs" update, the problems get worse.

Sorry if the message is too long, I just really want this to be fixed because it cost me $20.99 and I fell for a $21 game, there really shouldn't be that many bugs and crashes, I do know that Minecraft is relatively new to the Chromebook, but it seems a bit excessive

I was directed to Jira after submitting this same summary to Minecraft Support where     
Magileine M directed me here. Magileine told me that I encountered a bug because the second I open up any world, the application closes out with no warning or error message, ever
