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

Done!
Any news on how to fix this, I've looked at the duplicate MCL-13519 that you mentioned above and none of the 'fixes' in there have worked, such as restarting, reinstalling Minecraft and Java.... still nothing. Sorry if I'm sounding impatient, but I'm a twitch streamer, and Minecraft is part of my livelihood. Thanks for your help!
