CodePudding user response：

I experienced a similar problem. I uninstalled the 7.0.100-preview.5.22307.18 sdk using add remove programs and then changed the TargetFramework in the project file to use 7.0 and then I was able to load the projects.

You can try the following method：

1.Open the Visual studio installer.

2.Select the viusal studio repair function.

Hope it can help you.
