Sometimes after closing the game or when the game crashes, and you try to reopen the game it simply wont start back up, or you have to click the game icon tons of times to get the game to start up again. The only way to fix this issue is to completely restart your computer which is very annoying to do. 

Steps to Reproduce (Only works part of the time):

1. Open Minecraft Windows 10
2. Close the game (or have the game crash)
3. Try to start the game back up
