My launcher isn't working properly

My launcher isn't working properly i was playing minecraft normally then i went to eat so i closed the game when i came back the launcher won't open again and it doesn't showup on task manager either i deleted minecraft and reinstalled and it worked then when i downloaded a version and closed the game it won't open again so every time i download a version and close minecraft it won't open again i updated my driver but it' sno use i deleted mods but no use i tried everything

[it doesn't work with all versions not just that version i put in but i had no choice]
