PowerShellEditorServices: PowerShell Extension v2020.3.0 breaks with AppLocker

We are allowing scripts and executables in the extension folder to be run in %OSDRIVE%\USERS\%USER%\.VSCODE\EXTENSIONS. The below error happens with the new version, but this does work with the previous version. As a workaround we have reverted back to the previous version for now.

Exception encountered starting EditorServices. Exception logged in D:\a\1\s\src\PowerShellEditorServices.Hosting\Commands\StartEditorServicesCommand.cs on line 247 in EndProcessing:
