Design Problem in VS2022

Question

I just purchased a new Dell XPS and installed the Community version of Visual Studio 2022. Programs load and execute perfectly, but when an xaml file is viewed in the IDE, the XAML window shows the code correctly but the Design window shows the following error:

I have installed everything I know to install. I have run these programs on another older machine without a similar issue.

Thanks for any help.

System.Exception

Hi @Steve, 

Welcome to Microsoft Q&A! 

What is your project type? Please create a new project and check if it only occurs in the specific project or not. 

You can update your VS2022 to the latest version with Visual Studio Installer. Then, try to launch your Visual Studio 2022 in Safe Mode (run devenv /SafeMode in Developer Command Prompt for VS 2022). And check if the designer works normally. 

Meanwhile, you can close all running VS instances and try to delete the hidden .vs, bin and obj folders in the project folder. Then, clean and rebuild the solution. 

Sincerely,

Anna
