Glitching character (Fallout 4)

In general, I run with Piper. Glitch of this kind she doesn't run with me. Orders come here or here do not work stands still rooted to the spot. It will move from door to door across locations. Who faced such a thing? That just didn’t try. Let go, took another character, she doesn't care anyway! I did not install any mods, I did not change anything in the console, I updated the game, I thought it would help - it did not help (. Changing the settings from ultra to high and back is also not the same. By the way, I noticed that it lags on High and not on Ultra!
