Pupils unable to login - Error Message - An error has occurred

We also have a school getting this error. I’ve been through the whole of the forum post Signin Error - #3 by vineyb which seemed to relate errors we were getting a couple of weeks before this new error. Pop ups seem to be allowed - not seeing them blocked - and then any of the other fixes mentioned further down in the post don’t appear to be available - i.e. trying to follow the route to get to the settings mentioned don’t work. I did manage to finally find a setting about the Classroom API / Data Access but it was already on. The app access control for Sketchup is Trusted (Google Workspace MarketPlace). I’ll try logging a call with Sketchup Technical support but if anyone has any tips about resolving this error then it would be great to hear what you’ve done.
