Game launch issue

Hello,

I bought Minecraft recently and the game was working fine. But 2 days later I wanted to relaunch it, but when I arrive at the loading of Mojang, the loading bar does not finish and suddenly it puts me: "not responding" and I therefore cannot launch the game . Yet I have a minecraft launcher and everything works. As for the versions, I do it with all. I try to reinstall the game it does the same. I asked some friends but they couldn't find the problem. This is why I am coming to you. Thank you very much in advance.

cordially
