I have a Blazor Server project created with Microsoft Visual Studio IDE Version 17.2.0 Preview 1 and it was debugging and starting without any problems.

When I upgraded to Version 17.2.0 Preview 5.0, I am unable to build the project, run the project or even close the IDE. Popup UIs are showing up each time I try to do any of these actions.

I am now closing the IDE using the Task Manager. I have attached screenshots with descriptions and if anyone has ever solved this please assist me to get over this.

I have tried the following:

1. Created a new project but the problem remains.
2. Repaired Visual Studio IDE but the problem remains.

I am using:

1. Blazor Server and .NET 6.
2. The IDE is Microsoft Visual Studio IDE Community Edition Version 17.2.0 Preview 5.0

I will appreciate any help I can get.

The above error shows up when I try to debug the project:

The above error shows up when I try to close the IDE:

CodePudding user response：

I created a Blazor project in Visual Studio 2022 17.2.0 Preview 5.0, built the project and ran without encountering this issue.

Please try closing Visual Studio, deleting the project's .vs and bin/obj folders, and reloading the project.

If the issue still exists, please run /safemode at the development command prompt, it will check if third-party packages and extensions are causing the issue.
