CharacterMovement is suddenly broken.

I don’t recall doing anything strange outside of adjusting some values in my CharacterMovement details panel. However, it seems like I managed to brick my Character Movement component. When I run the game in the editor, my character is totally frozen, then after stopping I get these Message Log errors:

The Output Logs show:

Another thing that is strange now is when I click on my Character Movement component, the details panel in now blank.

What exactly happened?

Thanks!
