How to remove a dot?

Does anybody know how to batch remove the recurring dot in the middle of the picture ?

Just guessing: could it be that the camera has been pointing at an intense source of energy, like a laser-pointer? In that case you’d be looking at ‘dead-pixels’ on the sensor, which sounds like a professional repair?

How would you differentiate between dead pixels and a blemish on the screen protector or the lens?

No it was just a dirty spot on the window, or is it a windscreen ?
