Minecraft crashes, what to do?

I want to start Minecraft, but the only thing I see is the launcher. As soon as Minecraft opens I see for 5 seconds. A black screen, this closes again and brings me to the launcher. Get the following narchit: "Game crash" and "An unexpected problem occurred and the game crashed. We're sorry for the inconvenience. Exit Code: 0"

With the following options.

(Close) (View crash report)

I tried this 3-4 times. What do I do now?

Update: I can't find a way to put some of the crash report in here because it's over 3,000 characters long, so I need to know which part of it I'm sending in. Or I'll take screenshots of it and put it in here.

Can you send in the crash report?

Yeah yeah

If it is 3.00 characters long, I can't send it in completely. Can you roughly describe to me what you need? More accurate.
