It’s a stall. When the plane is like that it’s nearly impossible to maneuver because the control surfaces aren’t exposed to airflow so they don’t do anything. Your only hope is to somehow make it face the ground again and pull up in time.

As to how it got that way it usually happens when someone loses track of the horizon and tries to fly up.

Same happened with me but on YouTube! Reported an ad that was pretending to be fox news or something, led to a website pretending to be another news site that linked to a fake shell (the oil company) site to get your credit card information. Despite going very in depth about the scam “everything was fine”.
