In the Windows 10 version of Minecraft, whenever I launch it, without fail, I get a blank white screen after the Minecraft logo. The only way to fix this is to open task manager, click into the Minecraft app, right click 'runtime broker', and force quit it. 

I was able to find this fix from the following Reddit comment:

It does appear that plenty of other people have this exact error.
