Hello,
Thank you for posting in Microsoft Community forum.
Based on the description, I understand your question is related to KB5048671 issues.
I checked the KB5048671 update page but do not find such known issue published, however, there is a newly released update in January for Server 2016, which is KB5049993. You can try install this latest windows update and monitor the issue.
January 14, 2025—KB5049993 (OS Build 14393.7699) - Microsoft Support
Have a nice day.
Best Regards,
Molly
