Drone flips over after slow speed crash

I’ve only been flying for a couple months so I apologize if I say anything naive. I have a Potensic D85 that I finally crashed. It happened at a very slow speed and then fell to the ground. It was only about 6 feet up. On the ground two motors kept spinning while the two others stopped. Props looked ok and I didn’t replace them. I took battery out and reinserted. Motors all spin up but every time I try to take off it flips over. Any suggestions? I appreciate it.

r all the props tight.
