Swapping the Child Actor Class of a ChildActorComponent back to a previously selected BP leads to an Editor crash from illegal Renaming

A fatal error occurs if we change a Child Actor Class from one BP (ex. "BP_A") to a different BP ( ex. "BP_B") and later change it back to the first BP (ex. "BP_A") without compiling the BP between changes. This particular issue was tracked by the licensee as he was working on the Lyra project on UE5.4 and created a ChildActorComponent inside a SceneComponent inside B_ExperienceList. I could not reproduce in a clean project.

Error message (project specific info stripped)

Error: Fatal error: [...\Engine\Source\Runtime\CoreUObject\Private\UObject\Obj.cpp] [Line: 273] Renaming an object ('ABCDEF' /Engine/Transient.ABCDEF_C_1) on top of an existing object (ABCDEF_Old_C /Game/<Map>/<MyBP>.<MyBP>_C:ChildActor_GEN_VARIABLE.ChildActor_GEN_VARIABLE_ABCDEF_C_CAT) 

Steps to Reproduce
In Lyra 5.4 (could not reproduce in a clean project)
1. Opened a blueprint in editor (in this case it was B_ExperienceList3D but that shouldn't matter)
2. Added a scene component to blueprint
3. attached a child actor to that scene component
4. Set 'Child Actor Class' to a different blueprint class (will refer to as BP_A)
5. Open content browser, navigate to a different blueprint class and select it. (will refer to as BP_B)
6. In the edited blueprint, hit the 'Child Actor Class' arrow with tooltip 'Use Selected Asset from Content Browser'
7. In the content browser, navigate back to BP_A and select it.
8. In the edited blueprint, hit the 'Child Actor Class' arrow with tooltip 'Use Selected Asset from Content Browser' again to switch back to the BP_A reference.
9. Crash
