Here is what i got when i open powershell log folder

As you can see this folder does not contain any EditorServices.log file, only vscode-powershell.log, with same information as displayed above

Regards

[TylerLeonhardt]

Do you have any GPO rules in place that this machine is a part of?

[rkeithhill]

Does this yield any events that happened at the same time you attempted to launch the extension?

Get-EventLog -LogName Application -EntryType Error -Newest 10 | Where Source -match 'Application|\.NET' | Format-List *

[oliviermasson]

Yes my laptop is managed by my company, so GPO are in place.
But this is the case since few years, and i use VS with powershell extension since few years without any trouble.
I could check with my IT, but i'm not aware of any change in our GPO.

Here are the event log during my issue.
As you will see, nothing relative with VS:

I don't know if it's relative to my issue, but the error message when VS try to open a Powershell Integrated Console refer to a session timedout.

When i'm trying to open New Terminal
VS succefully and quickly open a powershell termninal, without any issue:

[TylerLeonhardt]

@olivermasson can you try this troubleshooting step for restricted systems and let us know if that helps?

[oliviermasson]

Hi @TylerLeonhardt

I've followed the troubleshooting step for restricted systems, and now I can tell you that there doesn't seem to be any GPO that prevents the import of the module, nor a signature problem, see next screenshot:

And it's the same for this module:

If it could help, i run Start-EditorServices.ps1 manualy.

[rjmholt]

Do you know when this issue started occurring? Was it followed by a PowerShell extension update, or maybe a Windows update or possibly after a VSCode update?

[oliviermasson]

Hello Robert,

I'm not sure, because I haven't used it in almost a month.
I know that when I restarted VS code, there was an update of VS.
I don't know if there have been any updates to the plugin.
I think there have been updates on my OS.

For the record, I have another PC (which is not managed by my company) and for which, the powershell plugin runs correctly.
Here is the information for this PC:
