Designer load encountered an error

Hi @Sandy Gordon, 

Welcome to Microsoft Q&A! 

What is your project type and the version of Visual Studio? Could you create a new project and check if it occurs in specific project?   

You can try the following workarounds:

1. Update your VS to the latest version.
2. Repair your VS with Visual Studio Installer > More > Repair.
3. Check the target framework.
4. Check that the project's references load properly.
5. Close all running VS instances and delete the hidden .vs, bin and obj folders in the project folder. Then, clean and rebuild the solution.  

Sincerely,

Anna
