Rigid body causes object to fall upwards

I added a rigid body to a cube with no script and with a collier but instead, it falls upwards instead of downwards. I have tried changing the mass to a negative number to reverse the gravity but when i run it automatically changes back to default.
Does anyone know why this happens and how i can fix it?
Im using unity version 2019.2,

By any chance, didn’t you make the camera itself rigid body? It happened to me, so it might be the issue

Your gravity should be set to a negative number

I tried doing that, yet, the objects are still falling upwards. i changed the editor, i tried to re-install unity and the objects are still falling upwards instead of falling downwards. can someone please help??? ;w;

Thank you so much, I had the same issue
