SSRS error on sign in ERR_UNEXPECTED

Hi All,

I have an error coming up when anyone tries signing into our company's Report Server Portal.  The error appears for one or two seconds and then the portal starts loading successfully.

This is from an Azure VM running Windows Server 2019 Datacenter.  Microsoft SQL Server 2019 (RTM) - 15.0.2000.5 (X64).  SSRS SQL Server Developer edition 15.0.1102.675.

Below are links to log snippets from one of the attempts at signing in.    This error occurs for all users and only on sign in, not while trying to run any reports.  At the time of testing the issue, there were no other processes running or users running reports.

Any guidance or tips would be greatly appreciated.
