Could not read projectid by clientid (AUTH-GHpw2)

Since sometime last week, I cannot create users via the API. Using v2.62.1 now, but upgraded with the latest releases a couple of times. Now my API request can authenticate and get a token successfully, but when I try to create a user, using either the v1 or the v2 endpoint, I get the following error:
could not read projectid by clientid (AUTH-GHpw2)could not read projectid by clientid (AUTH-GHpw2) My code has not changed so I'm assuming this is related to the latest releases of Zitadel. Please advise thank you.
