I don't get the autocomplete suggestions anymore in PowerShell. In the shell itself I only get a weird little dot where the suggestion should be and when I hit CTRL - spacebar in the script pane in PowerShell ISE I get an error saying "An unexpected issue has occured, and Windows PowerShell ISE must close." I've tried updating the help but that just gives me more errors.
A few months ago, PowerShell was working just fine so I assume it's since the latest update. Does anyone know how to fix this or safely reinstall PowerShell?
