Windows launch fails due to "Failed to find object" fatal error

Ok I fixed my issue; posting here in case someone down the line finds it helpful :smiley:

Using object finder will not work for cooked/launchable games because it’s reliant on that blueprint having been cooked before runtime and isn’t findable, so only seems to work in the editor from my understanding. Instead, I needed to use EngineUtils::ATL_Class as explained here. So for example, to find my BP, this worked:

TArray<UObject*> bps;
	if (EngineUtils::FindOrLoadAssetsByPath(TEXT("/Game/Beachballs"), bps, EngineUtils::ATL_Class)) {

		for (int i = 0; i < bps.Num(); ++i) {
			UObject* temp = bps[i];

			if (temp == NULL || (temp->GetName().Compare(TEXT("SingleCannon_C")) != 0))
			{
				continue;
			}
			else {
				MyBeachballCannonTemp = (UClass*)temp;
			}
		}
	}

The way to improve this is to template it if you need to find a bunch of BPs and to not hardcode the .Compare text like I did - see the link. This is how my subclass actor looks in my header so that I can spawn it whenever needed:

TSubclassOf<class AActor> MyBeachballCannonTemp;

and when I need to spawn the blueprint object:

AActor* BeachballBP;
FVector BeachballSpawnPoint = FVector(Mesh->GetSocketLocation("MidPoint").X-(SizeOfSquare*PercentageTemp), Mesh->GetSocketLocation("MidPoint").Y, Mesh->GetSocketLocation("MidPoint").Z + 380.0f);
BeachballBP = CreateBeachballCannonAtLoc(BeachballSpawnPoint);
