What’s happening?
The output variable for launching Chrome is blank, resulting in an error stating that the argument 'BrowserInstance' must be a 'Web Browser Instance'.
 

Reason:
This with the blank output variable for launching Chrome is likely related to browser cache or an extension malfunction.
 

Resolution:
For the blank output variable when launching Chrome:

  1. Uninstall and then reinstall the Chrome extension from the Power Automate for desktop designer, even if the extension appears to be present.
  2. Close the browser and manually execute the flow again.
