When a bug occurs, you can't move or resize keys anywhere on the curve or dope sheet.
Does not respond to mouse drag.
Currently the solution to this is to turn Unity off and on.
I tried reloading the clip file, changing the settings, changing the layout, or reloading the scene, but it doesn't work either.
If you are working on animation, it will be in the corresponding state at random. It is difficult to implement correctly. This happens every 3 days.
The project is large and restarting Unity takes me 10-20 minutes.
Please fix this bug. I have been under stress for a few days.
