How to fix exception from HRESULT: 0x8000000A for child window?

Question

Windows Forms

You need to create a second form.
Added to the project, made the display when you click on the button in the parent, when you start the second form is displayed, but in the studio it does not allow itself to be edited.
Says "The data needed to complete this operation is not yet available. (Exception from HRESULT: 0x8000000A)"
The main window runs smoothly.
Visual Studio 2017.
This is how I display a child window when clicked:

Form1 ^frm1 = gcnew Form1; 
frm1 -> Show();

Answer 1

It was decided, I just restarted the studio a couple of times and it worked.
