I can't use debugger with Visual Studio 2022

I am trying to debug something with my code. I followed a tutorial on how to debug with visual studio for Unity and he say to click attack to unity. But when I click attach to unity inside visual studio, I get this error: No connection could be made because the target machine actively refused it 127.0.0.1:56160

I am still new with Unity. I think I may have missed a step to make it work. Can anyone help me please?
