FKismetEditorUtilities::IsClassABlueprintInterface crash

I’m getting a crash here every time I try to compile from the editor in 4.26 (didn’t happen in 4.24). Is this a known issue? (Class is null and no null check).

bool FKismetEditorUtilities::IsClassABlueprintInterface(const UClass* Class)
{
if (Class->HasAnyClassFlags(CLASS_Interface) && !Class->HasAnyClassFlags(CLASS_NewerVersionExists))
{
return true;
}
return false;
}
