Missing Reference in Assembly Definition and NullReferenceException in AStar Componentdefenition

I’m running into a problem with AstarPathfindingProject in my Unity project.
Unity Version: 2022.3.22f1

Error after import:

System.ExecutionEngineException: String conversion error: Illegal byte sequence encounted in the input.

Error when hovering over AStar component in inspector:

NullReferenceException: Object reference not set to an instance of an object
Pathfinding.AstarPathEditor.DrawMainArea () (at ./Packages/com.arongranberg.astar/Editor/AstarPathEditor.cs:278)
Pathfinding.AstarPathEditor.OnInspectorGUI () (at ./Packages/com.arongranberg.astar/Editor/AstarPathEditor.cs:201)

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&)

Also missing one link in assembly defenition
“GUID:8a2eafa29b15f444eb6d74f94a930e1d” is empty link

Help

Is this a fresh import into a new project? As in the first time ever using the Asset or ever using it in this project? What version of Astar are you using?

I’d first try the import in a fresh updated 2022.3.53f1 project.
