So, I've looked at many bug pages about this problem, and tried every single one yet it still hasn't fixed my launcher.

Basically when I press play, it loads then it opens the launcher (New if I used the New one and Old if I used the Old one) then says: An unexpected issue occurred and the game has crashed. We're sorry for the inconvenience.

It doesn't let me look at the crash report since there is none, once I got it but when i clicked it, it wouldn't respond.

Steps to Reproduce

1. Click on any minecraft launcher
2. Use any version
3. Press play to start up the game
4. Stops and shows said text.

Yes, I've uninstalled java and reinstalled it, ran minecraft as administrator, uninstalled it and reinstalled it, used the setup wizard to "repair it", have the latest version of my graphics card, using Minecraft Vanilla, removed my .minecraft folder and re did it. I've tried absolutely everything I found online, and resorted to creating this account in hopes to find something that will fix it.

Yesterday I had the same problem, but with the uninstalling java and reinstalling it, the launcher seemed to work, but today when I attempted to do it again it just refused to work.

Before this was the output:

I just re did it and this is the new output with the same version:
