[lsp][bug] LSP sometimes won't successfully restart

manually running >TypeScript Native Preview: Restart Language Server can sometimes cause the LSP to fail to shutdown. I'm presented with the following error dialog in VS Code when this occurs.

fwiw tsgo --lsp zombie processes can also be left behind:

Is there any chance you could get an LSP message log from the output window, or at least the end of it (sanitized) when this happens?

mmm, not sure how helpful they'll be but here are some sanitised logs... the watched dirs are kinda odd to me as it's watching stuff outside of VS Code workspace root but don't think it's related to the problem.
