An unexpected error has occurred and the game has crashed

Won't open since I updated to the latest version of Minecraft (22/10/18). Just gives me the error message on the launcher.

 

I've updated to the latest Java, uninstalled and reinstalled Minecraft. Nope.

 

Also it doesn't like my double screens - keeps opening on the 2nd screen no matter what the settings (1,2; extended; duplicated), which if I don't have them both on and the extended setting selected is a hassle
