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

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.

Logs

No response

Inizia riproducendo il malfunzionamento con wait-debugger; & MyCommand nel debugger di PowerShell e ispeziona lo stack delle chiamate in pausa segnalato. Acquisisci i log dell’estensione e confronta il percorso di apertura dell’editor intorno all’errore cannot read properties of null (reading 'create'); il lavoro è completato quando la sessione di debug apre il proprio editor senza l’errore.
