There seems to be something wrong with the horizontal elevator, the plane can't lower the fuselage when descending, the only solution is to restart the game, please help me what is happening。

Here is the video I recorded:

In this picture, although my speed has reached the critical value, the fuselage cannot be lowered (the nose continues to be raised and cannot be lowered).
