I pressed the play button in Minecraft a lot of times, but the game can't start?

You can try to " restart " minecraft, by restarting I mean go to start menu and type %appdata% and find minecraft folder and delete it. You can save and copy your world first and delete the minecraft folders.

Try to remove any mods that you are currently using.

Make sure to update your Java.

If on the launcher the game might be downloading an update just taking a long time to load
also you might have had another application open using a lot of RAM

But i pressed it a lot of times, the game still does not run
