Describe the bug
On trying to debug using the "JavaScript Debug Terminal", a project that has quite a bunch of very large source maps, the debugger, debug adapter & extension host crash with: "Debug adapter process has terminated unexpectedly (Extension host shut down)".

To Reproduce
Steps to reproduce the behavior:

1. Debug a project with very large source maps using the "JavaScript Debug Terminal".

My project is proprietary, so I can't provide it directly as a repro, but I will see if I can mock something similar that exhibits the same behavior if you can't figure out what's going on from logs alone.

Log File

vscode-debugadapter-28a26b60.json.gz

It also sometimes produces a cpuprofile in the "Window" log of VS Code:

exthost-d35bd5.cpuprofile

VS Code Version: 1.85.1

Additional context
Wasn't able to figure out exactly why it crashes. As in, if it hangs the extension host, and gets terminated by something, OOM, or something else... Any ideas how to figure this out?
