UE5.6 PIE Widget ActionDomainOverride Load Fail

I’ve added the ‘ActionDomainOverride’ to a Blueprint (BP) that inherits from ‘CommonActivatableWidget,’ but it isn’t loading.

Upon checking the following line within the function TObjectPtr<UCommonInputActionDomain> UCommonActivatableWidget::GetCalculatedActionDomain():

UCommonInputActionDomain* CurrentActionDomain = CurrentActivatable->GetOwningLocalPlayer() == OwningLocalPlayer ? CurrentActivatable->ActionDomainOverride.Get() : nullptr;

The debug information shows the following for CurrentActivatable->ActionDomainOverride.Get():

+		CurrentActivatable->ActionDomainOverride.Get()	0x0000000000000000 <NULL>	UCommonInputActionDomain *
+		CurrentActivatable->ActionDomainOverride	nullptr ({AssetPath={PackageName="/Input/DA_LobbyInputDomain" AssetName=...} ...})	TSoftObjectPtr<UCommonInputActionDomain>

The file’s path is being found, but it is not being loaded, resulting in a null value.

Does anyone know the reason why it isn’t loading?

I believe it’s a problem that I have to manually load the DA_LobbyInputDomain file, even though once I open it in the editor it gets loaded into memory and works fine from then on.
