Oil problem Impreza 2014

Hello, I recently had my oil changed (1 month ago), and now, after only 1500 miles, the low oil warning light has appeared, and there’s no oil visible on the engine dipstick.

I don’t see any oil traces on the ground and no any abnormal smoke.

I find this situation very unusual and I suspect a possible leak. Do you have any ideas about the potential issue or suggestions to resolve it?

My car have 98k miles and I change oils every 5k miles

Thank you.
