No, no error. Its just silently crashing. The code after the loop is also not continuing.

print("amount children: " .. UIParent:GetNumChildren());
	
local children = { UIParent:GetChildren() };
	
for key, child in ipairs(children) do
	local name = child:GetName() or child:GetDebugName();
			
	if name then 
		print(key .. ": " .. name);
	else 
		print(key .. ": " .. "Not Named");
	end
end

print("done");

So in thise case after child number 223 it is silently erroring out and the done
is never getting printed.
