vscode: Code Helper High CPU Usage

Does this issue occur when all extensions are disabled?: Yes

I thought this might have been due to an extension since I ran disable-extensions and it didn’t happen that quickly, but after running Extension Bisect it happened, and gave me a message Extension Bisect is done but no extension has been identified. This might be a problem with Code.. As mentioned below this might have been because it attached to a process and was trying to debug a Node.js process. I noticed after I started Extension Bisect that the debugger attached only when I started Extension Bisect (I had an existing process running before that, that maybe failed to attach???).

VS Code Version: Version: 1.69.2 (Universal)
OS Version: 13.0 Beta (22A5311f)

Steps to Reproduce:

Unknown exactly how to reproduce this, but it happens pretty frequently. Shortly after launching VS Code the Code Helper process takes up a lot of CPU usage. It seems like this might be correlated to when I start debugging a Node.js process.

One more note, I’m running 2 processes: tsc --watch & nodemon.

Attached are some screenshots that might be helpful.

Please let me know what additional steps I can do to help debug/troubleshoot this.

Yeah, looks like it. Reopening and forwarding to @connor4312 for investigation

When this happens please use this guide to profile the extension host: https://github.com/Microsoft/vscode/wiki/Performance-Issues#profile-the-running-extensions
