Switching Possess between controllers

Development Programming & Scripting

Hi, I want my player to able to controll a drone. I am currently unpossing the player then spawning the drone. When I try to posses the drone it crashes. The player and drone both have seperate controllers

void ACharacter::SwitchToDrone()
{
	if (DronePawnClass && isInWorld)
	{
		this->GetController()->UnPossess();

		FVector SpawnLocation = DroneSpawnPoint->GetComponentLocation();
		FRotator SpawnRotation = DroneSpawnPoint->GetComponentRotation();
		TempDrone = GetWorld()->SpawnActor<ADronePawn>(DronePawnClass, SpawnLocation, SpawnRotation);
		TempDrone->GetController()->Possess(TempDrone); // This crashes
	}
}

Thank You
