I have no idea what’s going on but all the physics seem to be broken for the entire project, I have the empty sample scene with a sphere and a rigidbody and it won’t fall to the ground. I also can’t apply forces through scripts. It was working fine before and I haven’t touched the project settings for a while so I’m not sure what to do.
If you think you’ve modified a global physics setting but don’t understand what, then I would use the reset settings at the top-right on the menu to return to defaults. You can always undo that if it doesn’t help.
That said, I can see that you’ve turned-off “Auto Simulation” so Unity won’t automatically simulate for you, it’s expecting you to manually simulate in script.
