Character animation twitches

Hi all. I have some problem with character animation. For some reason, in the editor itself it twitches a little, although in mixamo everything is fine.
This is what she looks like in mixmamo, pay attention to her feet, they stand straight, there is no shaking

And here’s how the same animation looks in the project. It can be seen that the feet are trembling and slightly sinking into the ground.

Is it possible to somehow fix this? And why does this happen?

It’s probably a result of animation compression.
This looks like a good resource on the topic for unity: Animation Compression in Unity - techarthub
