Animation: “add property” button greyed out

Do you have a game object selected that has an Animator component?

Note that 2021.3 is out of support. If you aren’t on the latest 2021.3.45f1 I suggest upgrading to 45f1. Patch release upgrades rarely break anything.

The version I am using is 2021.3.45 and I tried it in a new project and it did not work. Also, when I open the animation page, the new animation


button does not appear.
