Since the new launcher update, everytime I click on play, you see the white Mojang screen. But then it crashes and it goes back to the launcher where it says the game crashed! My launcher log: http://paste.ubuntu.com/24034130/ . I haven't allocated more RAM and I don't have any mods or resource packs. Also downloading Optifine (which sometimes helps Minecraft issues) didn't fix this issue. I updated my video card drivers and updated Java, but that also doesn't seem to cause the problem. I searched if more people have this problem, and they do, but I could find any solutions to this. If anyone is able to help me it would be great! If you need more information, please ask.

EDIT:
When I try to play, in the Minecraft. map there comes an new NotePad ( I have a lot of notepads in my Minecraft map now) with the following information: https://paste.ubuntu.com/24084749/ . Maybe that gives more information?
