Adding float value causes 11 VS errors

I am watching the intro to programming with the pizza pickup, and I made a similar system, but when I add the rotationRate variable it generates 11 errors, no instance of constructor “FReadSurfaceDataFlags::FSurfaceDataFlags” matches the argument list, twice and then another one with UParticleModuleEventSendToGame, even though I never edited anything but my own class. Code:

#pragma once

#include "GameFramework/Actor.h"
#include "BasicPickup.generated.h"

//Took MYPROJECT_API out before class name and after class keyword.
class ABasicPickup : public AActor

	UPROPERTY(VisibleDefaultsOnly, Category = Pickup)
	TSubobjectPtr<USphereComponent> touchSphere;

 //If I remove this UPROPERTY, it works fine.
	UPROPERTY(EditDefaultsOnly, BlueprintReadWrite, Category = Pickup)
	float rotationRate;

	virtual void Tick(float deltaTime) override;


Are there any other errors about about ABasicPickup not containing a variable called RotationRate (note the upper case R)? If so, that’s another symptom of FName not being case-preserving (which we’re working on fixing!).

Yeah, it works now, I think it is the capital R.
