VS2022 The operation failed as details for project could not be loaded

Question

This error occurred unexpectedly when I worked on my Blazor project as usual yesterday. When I tried to clean, build, rebuild the project, the process hung with this message, and all dependencies in the project(Analyzers, Frameworks, Packages) has an exclamation mark.
Then I tried to use the Package Manager Console. The Install-Package command also results in the same error.
I searched the whole Inte.net looking for a solution, here's what I've tried:

• Disable ReSharper 2022
• Delete VS caches(the.vs folder in the root directory of the project) and build results(the bin and obj folders)
• Clear NuGet caches
• Unload and reload the project
• Reopen VS2022
• Move project to a new location(with no special character in the path)
• Open other projects
• Create new projects
• Restart computer
• Update VS2022 to the latest version
• Reinstall VS2022
• Use VS2022 Preview
• Uninstall VS2022 and return to an older version

None of these efforts worked.
To be mentioned, the do.net restore and do.net build command still works, and the VS2019 on my computer also works fine(but the current project is based on.Net 6, so I have to use VS2022).
To provide more information, here the result of do.net --info of my current VS2022(17.0.3):

I've been struggling with this problem for the whole night, driving me crazy.
Any suggestions or solutions will be greatly appreciated!

Answer 1

I also faced this problem. After uninstalling antivirus and clearing nuget cache, it's resolved.

Answer 2

in your project file comment out ProjectTypeGuids save and restart VS - it will reload then - not sure why it happens though.
