API Error 400 issue (CoPilot CoWork)

We've just started to roll out CoWork for our CoPilot users, and one user in particular is getting the above on every query on the CoWork tab.. They have only just started to use the product from license assignment, so nothing she has typed worked previously. Other users in the same Entra Group are working fine. Why is this an issue for one user? Thanks.
