  1. This is related to Office Online Server. Although there is no update this month for OOS, the Windows 2019 Server was updated, and now OOS is offline, and I can’t restore service. I have rebuilt the OOS farm with no success. The event viewer on the OOS server has constant warnings about ASP.NET 4.0.30319.0 with event code 3005, An unhandled exception has occurred.
    Are there any know issues with the Dec. OS updates and OOS? Thanks for any help you have to offer.

    1. Update – after further testing, it appears that the issue was the web front end server for an unknown reason. DNS is now pointing to one of the app servers (temporarily) so that Office Online service is restored to users. Not sure why the web front end stopped working with the OOS after the Dec 2022 Updates, but it did.

    1. Yes. This is a known issue in December 2022 CU for SharePoint Server 2019.
      The product group is investigating the issue.
