Account Protection Policy Unable to Save

The screenshot shows three failures: the policy review service cannot be reached, group assignments cannot be saved, and the WHfB policy save fails. Because small device or user-setting changes also fail, this looks more like a portal or Intune service transaction problem than an invalid Windows Hello choice. Check Microsoft 365 Service health and Intune tenant status, then retry in a browser window with an Intune administrator. Create a minimal test policy with one setting and no assignment; if it saves, add the assignment and settings separately to identify the failing stage. Review Tenant administration > Audit logs for the failed operation, timestamp, actor, and result. Verify the administrator has Intune RBAC permissions and scope tags for the policy and target group. Do not keep editing the policy while errors persist. If the minimal policy fails, capture the time, tenant ID, screenshot, and details and open an Intune support request.
