Animations not playing during Pathfinding

When I tried the Mesh Animator with the mesh pathfinder, I get a black screen and an error.

“Internal crash: TypeError: gdjs.evtsExt__NavMeshPathfinding__NavMeshPathfindingAnimator.NavMeshPathfindingAnimator.prototype.onCreatedContext.GDObjectObjects2[i].getBehavior(…).diagonalsAllowed is not a function”

I don’t know if I’m missing something but it says the behavior isn’t attached
