Debugger always fails to attach to VS Code extension host (`"type" : "extensionHost"`)

[minestarks]

Describe the bug

Recently, VS Code extension debugging using a launch.json configuration stopped working completely. This is with repos and launch.json configurations that used to work just fine (a few months ago?).

• I am not able to set breakpoints in .ts files
• I am not able to set breakpoints in the compiled .js files
• I don't see my extension code under "loaded scripts"

To Reproduce

1. Clone the official "hello world" VS Code extension sample at https://github.com/microsoft/vscode-extension-samples/tree/main/helloworld-sample
2. Open the folder in VS Code
3. npm install
4. Hit F5 in VS Code to launch the extension
5. Set a breakpoint in extension.ts
6. Set a breakpoint in out/extension.js

Observe that the breakpoints aren't getting bound.

Additional context

Originally encountered in when working in the Q# extension at https://github.com/microsoft/qsharp - but I did repro in every other VS Code extension I tried.

@connor4312 Is the attached log corrupt? I can't unzip it on my end. I tried a few times, but I'm unable to get VS Code generate a valid file. Sorry :/
