That error you are getting is very likely and issue (if not "the issue"); that error tells me you are using some sort external SSO authorization.
- I assume you have the latest Zoom App version installed, but if not, please do so.
- I would recommend, regardless of the previous step to uninstall the Zoom App; follow the instructions of the link below to do a "Clean Uninstall", but if you have enabled E2EE for your Voicemails, EMails, etc. then either don't use it, or make sure you save the information you need otherwise you will loose access to it. Try a regular uninstall / reinstall first.
Uninstalling and reinstalling the Zoom application:

You should not get any errors at all then login into Zoom Cloud Services.
