HELP -Failed Print -Large layer shift

Don't worry about the toy block. It wasn't blocking the printer or anything. It was but their so the cabinet door stays open.

I was printing this keychain. I wasn't at home. Turns out the print had this significant layer shift. Not sure why. You can zoom in to see the layer shift. It happened around layer 30 of 37.

I was printing with Kingroon PLA with a 0.4 nozzle on 0.16 High Quality. Speed was normal as were all other settings.
