I only play hardcore.
After losing a hardcore game, I delete the world and tried to create a new one.
Delete world - works
Game Menu - works
Create new world - complete selection, then
Game Crash
Can not exit game from Desktop. The only recourse is to restart Windows 10 and restart Minecraft.
This never happened before in earlier versions. 1.14.2 worked fine.
Thanks.
