MS Teams error code CA50021

Hello everyone,

I have a user who couldn't sign in to Teams, the issue was CAA50021, I've tried removing the device from Azure AD join and then rejoining the device and took time the device to join the azure again, I've also uninstalled Teams and reinstalled it and deleted the Windows login information, however the problem persists, does anyone have any other ideas on how to troubelshoot the problem? Could be related to conditional access?

Thanks in Advanced
