I can’t click or move in the animator.,I cannot click and move empty in animator

I ran into this issue too, and found that the problem disappeared in debug mode.

You can switch to debug mode from the "three dot" icon near by the "lock" icon on the title bar of the state property panel. (Don't know why, I can't upload the snapshot.....)

I was also just looking up this issue. Can't move any of the states in the Animator window. Hope there is a solution to this.

this bug is also on unity 2020.3.32.f1, but the update to 2020.3.33f1 solves it

hey there! I was just going through the same issue and got the solution by messing around with some combinations and one worked out actually ;) Just press the (alt) key along with left mouse click and the screen will move. enjoy peeps!

I ran into this issue and just about gave up hope when I saw this thread, but I found a dumb workaround: you grab them with another state using group selection and move them back into the working area.

For me, there was a small invisible box around the "middle" where I could still select things as normal, but all the states outside that were untouchable, like the editor wasn't receiving a mouse event or something. The reason I had states stranded out there in the first place was because I can still click and drag from within the box to outside, and I was trying to space them out for readability when they got stuck.

So, to rescue your states, you have to use another state that's inside the safety box (I made a new empty state), box-select the states together, and inch them back inside. As long as you have a working zone somewhere (you can test by attempting to box-select anywhere, because that only works if you start in a working space), you should always be able to get your states back from the cold, dark, vaguely-defined void.
