InvalidOverride

A method is annotated with the #[Override] attribute (introduced in PHP 8.3), signalling that it is intended to override a method from a parent class or interface. However, no matching method exists in any ancestor, so the annotation is incorrect.

Example

<?php
class Base {}

class Child extends Base {
    #[Override]
    public function process(): void {} // Base has no process() method
}

How to fix

Either remove the #[Override] attribute if the method is not intended to override anything, or fix the method name / add the method to the parent class.
