Admin console auth failed on iis after upgrade to 4.2.3

Product: PowerShell Universal
Version: 4.2.3

Hello!
We upgraded our installation to version 4.2.3 from version 4.2.1 and got the following problem: when trying to access the admin console it doesn’t load. No error appears, just a very fast page reload.

We have an installation on iis 10, we are using windows auth. I updated the product the recommended way: deleted everything in the C:\inetpub\wwwroot folder with a complete replacement of the contents from the .zip file and using the unblock-file commandlet. We have now rolled back to 4.2.1.

p.s.: Unfortunately, we can’t use kestrel because we need “silent” authorization using 2fa credentials and hardware tokens. Such authorization works only on iis.
