I am experiencing a problem with launching a powershell debugging session.
When launching a debug session, the powershell session crashes with this error (found it in the event viewer)
Error Message = The process cannot access the file 'c:\Users\avezina\.vscode\extensions\ms-vscode.powershell-preview-2019.12.0\logs\1578329950-8940193b-522e-41b2-b5f5-c1fce8b387181578329944994\StartEditorServices.log' because it is being used by another process.

Ok let me have a play with this this week. I know where it's occurring, so hopefully it's not too hard to work out why and how to fix it.
Screenshot of the error in the terminal:

Working through this (easily reproduced), I've fixed the initial issue but immediately hit another:

Looking over this, in the temp debugging scenario we don't create a language server on the basis that one isn't needed. However, the debugger requires the WorkspaceService, which requires the EditorOperationsService, which requires the language server.
Since creating a language server requires some configuration and networking, I'm not sure if just adding one will be the easiest fix. So I might invesigate with @TylerLeonhardt and see what the best solution is.
I've got a fix out for this one.
is it already fixed? Do I need to do something else than updating the extension?

It won't be available until the next release, which we're currently planning to do before the end of the month
