HUD is probably nullptr which you dereference.

That doesn’t say anything about HUD, the variable in your code.

Did you check if the issue was with HUD?

if (HUD)
{
    HUD->RemoveFromViewport();
}
else
{
    UE_LOG(LogTemp, Error, TEXT("HUD was nullptr!"))
}
#5

when i stop executing this Event BeginPlay in the ShooterCharacterBP It worked fine
so,maybe the error was causing in this blueprint

#6

im checking if its not a null ptr

#7

That only protects you from dereferencing a null pointer on the next line. If CreateWidget returned nullptr, you don’t dereference a null pointer when you attempt to add it to the viewport. However what’s stopping it in the code I mentioned?
