C++ Actor Components UPROPERTY's not showing in details panel

Hi, I encountered this problem also not long ago, here is the fix that worked for me (at least in UE 5.3.2):

1. First make sure your component is declared in the header file with EditDefaultsOnly or EditAnywhere, here is an example of mine:
   

2. Now go into Unreal and head to the problematic Blueprint class deriving from the native class.

3. Create a new Blueprint (following called NewBlueprint) and select the native class as base. Do not edit anything here, as we need it to open in the data only view.

4. Reparent your problematic blueprint to the newly created one (This is the part where it is important that the NewBlueprint has the exact parent class as the problematic one, otherwise you risk data loss).

5. Open the NewBlueprint, you should see your component property with the correct class assigned within the data only view. Compile & Save both blueprints.
   

   

6. In the NewBlueprint, change the class of the component to ‘None’. Compile & Save both blueprints starting with the NewBlueprint.
   

   

7. In NewBlueprint, click on the revert arrow to change the component class back to the former valid class. Compile & save both blueprints starting with the NewBlueprint.
   

8. Now if you click on your troublesome component, you should be able to edit the properties again.

9. Change the parent class of the problematic blueprint back to the native one and you should be good.
