Looks like an UI bug. Few others have reported similar behavior, and I can reproduce it myself. Use PowerShell or the API until Microsoft fixes it.

I am trying to add a Guest User on Microsoft Entra ID. I've done this hundreds of times in the past with no issue. Today I got on to add another user like I always do and got this message on the "Review + Invite" page. Along with a red dot above the properties pane.
"Validation failed. Required information is missing or not valid for following tabs: Properties."
But there is nothing missing from the Properties pane and no indication on the Properties Pane of what could be missing! What is going on?
