I had this error as well when using .NET 8.0 framework. I resolved this by adding the [ValidateNever] tag on the Actors_Movies property of the Actor.cs file. Here is the code snippet:

//Relationships
[ValidateNever]
public List<Actor_Movie> Actors_Movies { get; set; }

I believe the issues stem from changes in how model validation works in later versions like .NET 8 (the course uses 5.0) has evolved over time, and there have been updates and changes in model binding and validation behaviors.

it works how did you know that even chat gpt cant resolve it

I just did a lot of trial and error. Since taking the course, I have hit many issues, but each time with enough debugging and with the help of ChatGPT as well, I'm usually able to find a solution. The more issues you find, the more you will learn. Good luck!
