Objects are going upwards instead falling normally after I added a Rigidbody

i opened a project to work on some animation using unity for my videos. but the objects were going upwards instead falling normally when i added a rigidbody component even tho i changed nothing. does anybody knows how to fix the issue?? ;w;

thanks!

Are you sure you added the rigidbody to the object, and not the camera?

An object “falling upwards” sounds more like a camera falling down.

Unfortunately, no.
The camera is fine, its the objects are the ones that are going up.
I am not really a beginner to unity but thanks for the help! :>
