Shadows as when moving a window in Windows XP. How to decide?

Question

unreal engine

Good night everyone. There was an issue in Unreal Engine related to the "indelible" shadow from the character when moving. There was such a problem after connecting a blueprint with animation (including which has a blend space).

video of the problem

The light works on Lumen. I got such a problem with an empty project (Blank when creating) and in the ThirdPerson example. Also, it comes with another problem: the shadow is static and casts from the animation only during the movement of the character itself or the view with the mouse. I did not touch the settings of the project shown in the video, incl. Lumen settings.

Thank you in advance for your response.
