Ue5 should not been released yet?

I just installed it and couldn’t even use the editor. Every menu looked like the top left corner of the editor, and the whole screen quickly went black. I even verified the installation and changed my driver settings to be more compatible. I expected a 12.8GB download to function correctly. Yikes. BTW, I’m using an Nvidia 1080 Ti on a recent driver on Windows 10.
