Custom Gameinstance doesnt execute StartGameInstance

Hello, I recently tried to debug someone’s gameinstance and when I put breakpoint in void UBaseGameInstance::StartGameInstance() it didn’t stop. What could be possibly issue.
In headers there is: virtual void StartGameInstance() override; Is there any flag to prevent executing StartGameInstance? Maybe in bp Init prevent it.

I acknowleged that maybe that gameinstance is not set in ue4. Where should I search for it?
