Camera switching to second camera in scene when I change scenes or try to restart same scene

I have go 2 cameras in my scene, my main camera which is my player camera, which comes from the XR Origin Rig. My second camera is attached to a drone which is being shown on screen with a render texture.
Anytime I try to scene change to a another scene that is set up exactly the same, my camera switches to the drone camera view and I have no idea how to stop it happening. Even when my player ‘dies’ and I restart the scene I am in, it switches cameras.
If anyone has any advice or ideas how to stop this from happening that would be amazing, it’s really hindering the progress of my game as I am stuck in one scene!
