Repeating steps:

1. Use vscode command "File: new untitled text file" or use keyboard shortcut Ctrl+n to create a new unsaved file.
2. Set the language mode to "LaTex (latex)".

And the texlab server would crash while giving following notifications

1. Request textDocument/documentSymbol failed.
2. Client texlab: connection to server is erroring. Cannot call write after a stream was destroyed
3. The texlab server crashed 5 times in the last 3 minutes. The server will not be restarted. See the output for more information.
