Unified Service Desk Closes When Connecting to Dynamics CRM

Hello,

I am running USD 4.1.1.1319.  After network updates the application closes as part of the logon request.  I need guidance on what to look for as there are no event entrees on the application servers. Our ADFS servers and two-way trust appear to be working as expected.  The error from the logs is below.
======================================================================================================================

Source   : Microsoft.Xrm.Sdk
Method : .ctor
Date       : 1/23/2024
Time      : 12:40:37 PM
Error      : Value cannot be null.
Parameter name: securityTokenResponse
