Spaghetti blob. Could be delamination, as has already been pointed out, but the one or two times I’ve had this happen, it’s because the nozzle caught a raised drip-blob or slightly warped edge on the unfinished print and gave it a shove, then continued printing in thin air.

This is tough to diagnose without seeing how it was sliced. Could you take a screenshot of the model in your slicer, using the view that shows what it looks like after being sliced?

Looks to me like you had a delamination. Then it just squirted unconnected plastic after that. Sure you got the temperature right? Nothing might have caused your line to feed incorrectly for a minute? Last time it happened to me it was because there was too much drag on the feed. It had fallen off the bearing onto a screw, which let it keep feeding, but with extra drag.
