Put a new filter on fill with oil and start it again . Bet you it was the filter... can’t think of anywhere else it could come from if you didn’t disassemble the engine and it ran fine before.
Yeah its strange, ran fine 2 weeks ago no issues with oil leaks whatsoever, I would guess a leak would star small and get worse over time, this car dumped 4 or 5 Quarts in under a minute.
