I finally found the way to fix it and keep everything how it was before the bug.
Hold the power button until the computer turns off and then press the power button back on. Repeat that three times until you get a new page that lists a few options. The one you need is the Recovery Envirnment. Once there click into troubleshooting and then click Reset Computer. It will go through some stuff and then you computer will be how you left it before the update.
