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

[Rom265]

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.

We don't have great debug state syncing between the extension terminal and LSP just yet (it's a work in progress PR). Without more info to debug, I can only suggest using the VS Code debugger UI to set breakpoints and debug whatever you're trying to.

I reverted to the previous version of the Powershell extension and it has not happened since.

I can confirm, that i face the issue with the VSCode debugger and breakpoints as well. If you want to Step-Into a function, vscode falls into the described issue in that post.

I also can confirm the resolution of @Rom265 : Switch back from Version 2025.0.0 to 2024.4.0

@LKo-exp4 is it specific to wait debugger or are you using a launch configuration? Can you record a reproduction? In Windows 11 you can hit win-shift-R to get native recording and it's pasteable directly into github.

I confirmed that I have no issue using Step-Into etc. with v2025.0.0 and PowerShell 7.4. I also tried Wait-Debugger; & Get-ChildItem (and a command that came from a sourced script) with no problems. We need further repro steps / logs to look into this. Thanks!
