Hi @yinjiehe01, Can you reproduce this issue again and share the OmniSharp Log from the VS Code Output Pane? It contains a lot of information which will help us troubleshoot the problem.

@yinjiehe01 Sorry, your screenshot is the Razor Log, can you change to the OmniSharp Log in the dropdown?

This is a dupe of AzDo: [Bug 1545938][WebToolsE2E] After installing SDK 7.0, there will be some errors when opening the .cshtml/.razor file in the project.

Looks like a fix has gone into Roslyn (https://github.com/dotnet/roslyn/pull/61675). This should be resolved after we take a new build of O#.
