PowerShell Integrated Console does't start: Running the contributed command: 'PowerShell.ShowSessionMenu' failed.

Issue Description

The PowerShell Integrated Console does not start at all. The problem occurs with every single start of VS Code on my system. So I didn’t manage to get the PowerShell Integrated Console running once. There is a notification saying:

Running the contributed command: 'PowerShell.ShowSessionMenu' failed.

Screenshot

I have test the PowerShell and the PowerShell Preview extension seperatly and the problem occurs with both.

This is a fresh portable installation of Visual Studio Code with (only) the PowerShell extension. Although I have also tested the global installation of Visual Studio Code on my Windows system. I deleted the directories %USERPROFILE%\AppData\Roaming\Code and %USERPROFILE%\.vscode in advance to reset VS Code. The results were the same as with the portable version.

I have added all required and some extra information down below according to the template. Please tell me if I can provide any more useful information!

I have found I can temporarily resolve the issue on my system by deleting the contents of the following directory, then it will work once:

%AppData%\Code - Insiders\User\workspaceStorage

If I close VS Code or kill the terminal, I need to clear that directory again. For anyone else with this issue, it is a temporary workaround at least.

I just noticed that somebody created an issue about the exact same problem right before me (#3186), but I hope the additional information I provided is still useful.
