I don't know what causes this, just set an active camera using eyedroper and lock this camera to view. Then I can't see anything with this camera.
The camera setting is default.
I discovered that using local camera and press numpad 1 to turn the view into front view, it shows the unit of the scene is kilometer. But my scene unit is meter.
I pressed shift c to recover the view and press numpad 1 again. The scene unit turned back to meter. But the camera still can't see anyting and can not move.
Exact steps for others to reproduce the error
I don't know how to reproduce it, but I can provide my project file.
