Laravel 12 – “Target Class [X] Does Not Exist” Error? Here’s How to Fix It

I recently came across the Laravel error:

Target class [X] does not exist.

This usually means Laravel is unable to resolve the class you're trying to use. Depending on the situation, the cause can be:

Wrong namespace or missing use statement Incorrect class name Middleware/controller not found Incorrect middleware registration or alias Cached configuration/routes

I put together a short 4-minute walkthrough showing how to identify the actual cause and fix the error in Laravel 12.
