Popup stuck on screen when logging into Office365 and using Edge

When I go to Office 365s Outlook, Teams etc. Get passed the login prompt and it starts loading the web apps. At that point the "Save in 1Password?" appears to save god knows what that credential is. Pressing the X will not close it and its stuck there forever.

This only seems to happen on my Edge browser. The popup also happens in Firefox but pressing Close actually gets rid of it.

Latest build of Edge, 1Password (msix edition) and 1Password extension.
