IntelliSense and code analysis broken with 2.33.17

[austin-beer]

Type: Bug

Issue Description

After upgrading to 2.33.17, Intellisense and code analysis appears to be broken for all of my C# projects. The error occurs at some point while the language server is processing my workspace, since some code has obviously been analyzed and some has not.

Downgrading to the previous version fixes the issue.

Logs

I turned on dotnet.server.trace, restarted VS Code, and loaded one of my C# workspaces. The associated logs are here: 20240613T074614.zip.

Environment information

Me too, worked fine all day yesterday today I just have walls of yellow and red lines on a project that builds and runs without errors, this constant churn of functionality is incredibly frustrating

[ikrammert]

I have the same problem, I change back the version and works fine.

[chpoit]

The pre-release (2.34.10) version seems to fix this too

A couple followup questions to anyone hitting this

1. Is this occuring in all your solutions, or just certain ones? If only in certain ones, would you be able to share them (and what kind of projects are they)? My microsoft email is dabarbet@microsoft.com if you'd prefer to share privately.
2. Are you using C# Dev Kit, or C# standalone? If using DevKit, which version, and are you seeing all your projects loaded correctly in the sln explorer?
3. Would you mind sharing info on what additional errors/warnings you're seeing? E.g. a screenshot of the new error details

+1. I am using C# Dev Kit (v1.7.27) and experienced same problem. Rolling back to previous version fixed the issue.

Below are my points for my issue: 1) It is happing for a typical 3 tier asp Netcore 7 web Api application. 2) With C# Dev Kit. 3) Giving random error like "Method not found", "Task<> not found etc", Unbale to detect all the methods of any interface.
