Windows 11 Unavailable pin

[orchidsartanddesign]

My computer was being super slow, and I typed in misconfig in the search bar on the screen after it let me in. Then I checked a bunch of boxes that were running after hiding some boxes that I didn’t want to stop running, and now I can’t access my computer. It says that the pin is unavailable. What do I do?

What does clicking 'Set up my PIN' do?
