Error opening forms in source (help)

[kriteus]

Whenever I open some form in source, I get the following error

The designer could not be shown for this file because none of the existing classes in it can be created. The designer inspected the following classes in the file: FrmClass --- The base class 'Intersect.Editor.Forms.Editors.EditorForm' could not be loaded. Check that the assembly has been referenced and that all projects have been created.

 

Visual Studio Community 2019

Right after I compile, it pops up a bunch of errors like I can't find the exe files.

 

I tried to clean the solution too, but the error persists

 

@ Edit
sorry i got it after cleaning solution then rebuilding solution. It worked, thanks

If you haven't compiled the solution before, then there's your answer.
Rebuild the solution, only after that you will able to edit the forms with the graphic editor.
