Launcher is infinite, will not load all of the way

As stated by ZAmine in the launcher bugs, the loading is infinite, it will not stop and it will not load. I looked up on YouTube how to fix this, and to my surprise, it worked. Not for long. When I went to launch it the next time, the launcher took the whole screen, and now, you can't do anything except just sign out of my account or turn off the computer. (Look at ZAmine's report for the picture)
