I can’t find a resolution for that mistake

Question

I have a C# program and it is giving MANY bugs different, I’ll send everyone here, as follows:

Code Error: Description:

So come on.

internal AcessoAdd()
{
    InitializeComponent();
}

Error: System.ComponentModel.Win32Exception: 'Error while creating window identifier.'

Correction: I changed from Ternal to Public

Description: this code was already there, I tried to format the PC as recommended, I tried to tinker with regedit and increase the amount of window identifiers allowed, but nothing helps.

UsuarioForm usuForm = new UsuarioForm();

Error: System.StackOverflowException

Description: Usuarioform as its name already says, is a form, I create a variable to then open it but this error happens and I’ve tried everything also to make it work.

For now that’s it, you’ll probably have more after you fix this one, but someone knows how to answer me these two?

Answer 1

Check if you are importing the namespaces.

The classes User and Acessoadd both are in a different namespaces than the Pecscon.

If, for example, they are in a namespces called Users and Accesses respectively, try this:

    using NomeDoProjeto.Usuarios;
    using NomeDoProjeto.Acessos;

Answer 2

remove

internal UsuarioForm()

place

public  UsuarioForm()
