Debugging Remote Runspace: the editor could not be opened due to an unexpected error: cannot read properties of null (reading 'create')

まず、PowerShell デバッガーで wait-debugger; & MyCommand を使って失敗を再現し、報告された一時停止中のコールスタックを調査します。拡張機能のログを取得し、cannot read properties of null (reading 'create') エラーの前後にあるエディターを開くパスを比較します。デバッグセッションがエラーなしでエディターを開けば完了です。

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

I try to run a script with

wait-debugger; & MyCommand

(where & MyCommand stands in for some command), a tab opens in VS Code with a red circle with an X. It says, "the editor could not be opened due to an unexpected error: cannot read properties of null (reading 'create')" with a "Try Again" button.
I have seen this a few times recently. If I close and reopen VS Code (a frequent fix for when it bugs out), it still keeps doing that.
It looks like an error from VS Code, but it happens when I'm trying to run the debugger with Powershell; so, it probably makes most sense to post this here first.
