Phone won't charge properly

Charging goes on and off constantly and you need to have the phone and charger in a very specific position in order for it to charge. I already tried different chargers and tried to carefully clean the port with a toothpick. Also tried just turning it off and on again and charging it without the phonecase incase that was the problem. Neither worked. The phone does charge but you can't move it around much or it goes off again.

Any ideas? My phone is less than a year old. It's a galaxy A14 5G.
