Use F7 button to toggle between Design View and Code View.

You should not edit Form1.Designer.vb file. And be sure there is at least the following lines exist.

Public Class Form1

End Class

(Here, I am taking your Form as f1)

To view the design, just go like - View>Solution Explorer>f1 (double click on f1 to open its design).

---

Click the button in Solution Explorer - Folder View to "Switch between solutions and available views" and then click on the form file.

---

F7 to toggle from design mode to code Shift + F7 to toggle back to design mode

I realized the issue appears (at least for me) when there are multiple classes defined inside the .vb file.

To solve the issue you have to make sure the Form class is the first (right after the imports). Move any other class definition below this class and forms designer will become available again.
