Canon EOS 77D Error 50 bent pins?

[jgs816]

I am getting an error 50 on the screen whenever I try to use the flash. 

Is the first pin bent in the battery compartment? Could this be the cause?

 Would the external flash draw power from the camera battery or does it have its own power supply? I may try an external flash.

External flash has its own power supply.

Thanks for the tool suggestion. I have tried to bend with small pliers, but it just keeps bouncing right back to this position. I agree, I am worried about fatigue so I wont attempt it anymore.

The battery still powers the camera and works without the flash. I have no idea how it got twisted. I I only used the standard battery that came in the box.

Does the 77D have the switch in the hot shoe that detects the presence of an auxiliary flash or other accessory installed in the shoe? Is the switch possibly stuck in the down position or is there any debris in the channel where the flash mounts?

Just an update guys. I purchased an external flash as suggested above. This has solved my problem. Thanks for your help.
