Crash problem when launching the game

Hello,
as say in the title I can not launch minecraft for a few months with the new launcher, I stayed on the old one that unfortunately does not work either. What happens, I run minecraft I arrive on the launcher and I launch any version of the game. Then they are two possibilities :
-The launcher closes and nothing happens. (if I re-open the launcher he tells me that the game is already started)
-the game launches but crash when loading the game (the screen with white background where there is written minecraft and the logo)
I have already tried to uninstall / reinstall the game, delete files, stop my antivirus, restart my pc.
I am under Windows 10. Thank you in advance.

(the version of the new launcher is 2.0.1003
