unity3d – No more than one transition can be created in a state

I am using version Unity 2020.3.31f1 Personal.

I created an animation clip in which the character walks, runs and stops.

Now all you need to do is create a transition in the animator controller and set the parameters.

But a problem arose.

Only one transition can be made from a state.

Currently my status looks like the picture below.

Entry   →   stops   ←→   walk
              ↑
Any State   jumps                    Exit

No more transition created in stops state.

If you right-click on stops, the Make Transition context is not visible.

Is there any additional information I need to provide to resolve this issue?

If you know a solution, I would appreciate your help.
