I was playing Minecraft on stream last night, and when I finished, I shut the game down and reloaded it. The Launcher loaded as normal, and when I clicked play the green loading bar appeared at the bottom, flashed up to about half-way and then disappeared. The game did not launch. There was no error message or crash detail. 

I have since uninstalled and reinstalled both Minecraft (entirely, including deleting the .minecraft folder) and also Java. I have updated java to it's most recent edition and I have also updated my NVidia GeForce drivers. Yet still the game does not open.

Update: Attempted a new Minecraft custom installation on the launcher, this did not fix the issue.

Update: Launcher.log text file added & launcher_cef_log too

Would appreciate some help for this!

Thanks
