https://github.com/Microsoft/python-language-server/blob/4a00ee80cb2d7b3e736329e82b2ed441ae70b5ca/src/Analysis/Engine/Impl/Intellisense/AnalysisQueue.cs#L60-L71

When an unhandled exception occurs, and it's deemed "noncritical", the error is logged and then the AnalysisQueue gets disposed. However, the users of the queue have no idea this is happening and will continue to use it. Specifically, the language server will get requests which only lead to ObjectDisposedException.

I'm not sure what the correct behavior is here, but if an exception occurs and we are choosing to dispose of the queue, then I feel like either a new queue needs to be created or the server needs to shut down.
