Rigidbody not show in Component Section,Rigidbody not showing on Component Area

Hi,
I opened a new project to make a game. When I wanted to create a rigidbody for an object it would not show up in the component section of the Inspector. I then tried this for multiple objects and it did not work. I have made tons of rigidbody’s before and never had this issue.

I’m confused, so here is a screenshot.

Hello.

This is so strange… Are you sure you installed unity with all basic packs/addons?

I recommend you to resinstall Unity (look for some youtube tutorial to be sure you are installing it correctly)
