MyCharacter class wont reflect correctly in Level

[ajinkya_x]

This is my first time using Unreal Engine. (I’m using 5.5.1)

I deleted the default Player Start component.
Created class MyCharacter, and a blueprint (PlayerCharacter) which inherits MyCharacter class.

I added camera and spring arm. which I can see in the Blueprint preview section, but still camera is nto child of Spring arm even though in the code I have made it CameraComp->SetupAttachment(SpringArmComp);

And main issue is in Game mode I can still fly while I deleted Player start, and camera is not what I expected.

I fixed it by recreating the blueprint.
