As it might be caused by "Installing the PowerShell Extension on Restricted Systems": with "pwsh.exe"

Import-Module $HOME.vscode\extensions\ms-vscode.powershell*\modules\PowerShellEditorServices\PowerShellEditorServices.psd1

Import-Module: Could not load file or assembly 'System.Runtime, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.

with "powershell.exe" the above import-module runs without problem.

Our own scripts work, not sure if they use System.Runtime, but I think this is minimal needed to run.

I need PowerShell 7, what is missing to load the assembly System.Runtime for the PowerShellEditorServices.psd1 script ?
