Language Server Becomes Unresponsive After Opening Command Explorer

Prerequisites

I have written a descriptive issue title.
I have searched all open and closed issues to ensure it has not already been reported.
I have read the troubleshooting guide.
I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
If this is a security issue, I have read the security issue reporting guidance.

Summary

PowerShell intellisense works until I open the command explorer once. The command explorer never populates, and I have to close the command explorer and restart the PowerShell session to get intellisense working again.

It will then send a textDocument/completion message when I do Ctrl + Space, but it will never receive any response, even after several minutes of waiting.
