In the JohnLemon guide, when baking NavMesh, it is not displayed, and errors occur because of this

The error is: "GetRemainingDistance" can only be called on an active agent that has been placed on a NavMesh. UnityEngine.StackTraceUtility:ExtractStackTrace () WaypointPatrol:Update () (at Assets/Scripts/WaypointPatrol.cs:21)

-All baking objects are static -Script is literally the same as in guide -NavMesh Display checkbox is enabled

I think something is wrong with the project, bcz I cant even see another NavMeshes on other new objects Please, help, how can I fix that NavMesh is not baking correctly?
