the props don't tie perfectly, the drone shakes too much during the flight

[hazemha]

Hello,
I'm a beginner with FPV drone, but when I fly with it it is shaking too much, and after 2nd or 3rd flight, I always found the drone props damaged, I don't know why but I think I did something wrong, And I hear a whistling sound when I put the camera(GoPro Black 10) one of the props was unscrewed.
I will share videos, I hope to see your comments.

Install your props properly? None of them seem actually tight...
