The Detail Panel shows no information

This is a C++ based Unreal Engine 5.3 project.
At some point during configuring Blueprints, components created through C++ editing show no information in the Detail Panel, and when spawned or placed in the level, the editor forcibly shuts down.

and Engine send log message is
“LogScript: Warning: Accessed None while trying to read the CharacterMovement property.”

Is there a solution?

In my opinion, it seems like all properties have been removed…
