That error generally indicates that our web cookies aren't working for the student. Typically that happens because Canvas and Schoology forces us to launch worksheets while surrounded by their interface. And since we're embedded like that, the cookies we use are considered "third party cookies."
Some browsers like Safari block third party cookies by default. In Chrome, they tend to be allowed, but it's entirely possible your IT organization has decided to block them. And it's possible that the student is launching in Incognito mode in Chrome, where third party cookies are blocked by default.
