Every time I click on the newgame or loadgame button, this crash happens:

Hello there @Aeldron!

Checking around the community for similar scenarios, that looks like a null pointer error, which means that UE is trying to access an object that is not initialized.

The crash log points to line 36 of “SlotsWidget.cpp”, so the first step would be to check your code on said line. Please make sure the pointer as a proper targer assigned. You can also add a null check to that section, something like this:

if (MyCode)
{
MyCode->DoSomething();
}
else
{
UE_LOG(LogTemp, Error, TEXT(“MyCode is null!”));
}
