     Hi @Janith Sahasra , 

    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 new project?  

    Then, you can try the following workarounds:

    1. Update your VS to the latest version.
    2. Repair your VS though Visual Studio Installer > More > Repair.
    3. Switch to higher target framework for your project.
    4. Please check if the project's references load correctly.
    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.  

    If the designer still failed to load, please share us more details or screenshots to investigate it further. 

    Sincerely,

    Anna
