Hi. Copilot in my VSCode stops working after a few minutes.

Let's say I open up VSC and write something, asking Copilot for suggestion, then it works ok for some time. If I take a break for 3 minutes, Copilot is not responding anymore when I ask it for suggestions.

I don't know if it's relevant, but I trigger copilot manually.

What's also interesting is that when it gets stuck after a few minutes of launching VSC, any new suggestion I ask for doesn't generate anything in the GitHub Copilot output. No [fetch completions] is sent, there doesn't seem to be anything wrong on the server side, it's not like VSC is waiting for response which is not arriving. It's more like I do my keyboard shortcut to ask for a suggestion, and the extension doesn't react to it. Although the little Copilot icon in the bottom right is spinning, there is nothing new in the output console, so once it hangs, that's the last output logs I'll see.

I tried clean install on Windows, purging both Windows and WSL caches with anything related to VSC, switching to pre-release version.

Please help me, because I'm losing my mind.

Here are relavant fields of settings.json.

"accessibility.verbosity.inlineChat": false,
"editor.inlineSuggest.enabled": true,
"editor.inlineSuggest.showToolbar": "always",
"editor.inlineSuggest.suppressSuggestions": false,
"editor.suggest.showInlineDetails": true,
"github.copilot.editor.enableAutoCompletions": false,

Here is the output from diagnostics

And here are a few lines from the output section when I triggered suggestions a couple of times, everything looks ok.

after that, when the extension gets stuck, no new logs are generated.
