NavModifier cannot move with player
add a NavModifier component to player pawn, set "Navigation Mesh/Runtime/Runtime Generation" to "Dynamic Modifiers Only", play in editor, and toggle "show Navigation", then can see the navmesh does not move with player:

After investigating this issue, I do not believe that it is a bug. If you notice, the component is not a scene component, which means it's not necessarily attached to the component hierarchy that you have set up. As a result, I wouldn't expect it to move with the character. Navigation Modifiers, in my experience, have been used more as a way to alter the Nav Mesh in a specific, static area.
If you'd like your character to create a hole in the Nav Mesh, you can try setting Can Ever Affect Navigation to true and that should give you a similar result based on the character's capsule collision.
Have a great day
