Post the code here, you can make a

[rain plinth]

That's the "wrong lerp" (https://unity.huh.how/lerp/wrong-lerp) that probably causes it. When the distance between the cube and the object hold position changes the lerp behaves erratically. Try using MoveTowards instead

so MoveTowards is my best bet in your opinion ?

[rain plinth]

It's worth a try

[alpine lake]

ok thx ill try it and tell you what happens

[pallid ibex]

Rigidbody.MovePosition doesn't belong in update

Physics must happen in FixedUpdate

Also does your player character have a Rigidbody?

[alpine lake]

yes

[alpine lake]

oh so i put everything related to physics in fixed update ?

[pallid ibex]

So you have an issue there where you're directly modifying the player's transform in your rotation code which will break interpolation
