Can't Login in Unity Editor

[fleet zinc]

Brand new to Playfab and Unity here. I'm following this: https://learn.microsoft.com/en-us/gaming/playfab/sdks/unity3d/quickstart

I'm following the portion that uses the Unity Editor Extensions Asset Package. I get to step 5, where I try to log in to Playfab within the Unity Editor.

My Playfab account is a Microsoft account. So I hit "Log in with Microsoft", which changes the menu to the one in my attached screenshot. I put in my MS account credentials and hit the Log In with Microsoft button. But I get the following error in the Unity console:

Microsoft.Identity.Client.PlatformsCommon.Shared.DesktopOsHelper.GetWindowsVersionStringInternal () (at <95dac0a1c9714151aa78d3fb3ed442c0>:0)```

Any thoughts on what might be wrong?
