What potential pitfalls can arise from incorrect object instantiation and method calls in PHP scripts, as seen in the provided code snippets?

Incorrect object instantiation and method calls in PHP scripts can lead to fatal errors or unexpected behavior in the application. This can happen if the class is not properly instantiated or if the method is called on a non-existent object. To solve this issue, ensure that the object is instantiated correctly before calling its methods and double-check the method names and parameters. 

// Incorrect object instantiation and method call
$object = new MyClass();
$object->myMethod(); // This may cause an error if MyClass is not properly instantiated

// Correct object instantiation and method call
$object = new MyClass();
if ($object instanceof MyClass) {
    $object->myMethod();
}
