Are those script errors looking like Internet Explorer errors ? if so, this could stem from an incompatible browser setup on the user's workstation.
Try to disable from the home page 'customize this page' the 'Connect' option, as this opens a browser session to the Microsoft web site and the content might not be properly rendered by the IE engine.
Microsoft had announced the removal of IE 11.x sometime ago and it should be replaced by Edge, but GP uses its own library / IE engine for the Connect pane apparently..
It is http://um01.qcloudteo.com/beacon.min.js and other people are related to some temp files in c drive.
Why GP is try to access http://um01.qcloudteo.com/beacon.min.js???
