Using NewObject inside PostInitProperties and creating a BP of the class will cause the editor to crash on PIE if the BP is is set in gamemode defaults
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Test) UCapsuleComponent* PlayerComponent; virtual void PostInitProperties() override;
void AMyPawn::PostInitProperties()
{
Super::PostInitProperties();
PlayerComponent = NewObject<UCapsuleComponent>(this);
PlayerComponent->AttachTo(RootComponent);
}
Result:
The editor crashes after clicking Play button
