Error 500 for important site using Chrome on Chromebook

[pipcart]

Hi, Chrome has started giving an error 500 when I visit Google Classroom on either my Chromebook or PC. It started on my PC and then spread to my Chromebook a few hours later, so I am guessing it spread via sync. It is OK in Firefox on my desktop and, for now, it is OK on my friend's computer.

I have obliterated all browsing data, cookies, etc., run incognito and still can't get to Classroom.

Any ideas, please? I am particularly keen to fix on Chromebook, since Chrome is my only browser on that device.
