Windows 2012 DC rebooting at random times

Over the weekend, I installed the latest Windows Updates on my DC running Windows 2012.  When I view my Update History, I see that KB5009586 and KB5009720 were both installed.  I have since uninstalled KB5009586. When I look at installed updates, I see the following Microsoft Updates are still installed from over the weekend:KB5008881, KB5008865, KB5008888.  My DC is still randomly rebooting with the following message in the Event Logs:

The process wininit.exe has initiated the restart of "My computer" on behalf of user for the following reason: No title for this reason could be found.  Reason Code: 0x50006.  Comment: The system process 'C:\Windows\system32\lsass.exe' terminated unexpectedly with status code 255.  The system will shut down and restart.  Event ID: 1074. 

Should I uninstall the other updates that were installed?  I haven't seen anything online about those yet, but after uninstalling KB5009586, I am still seeing the server randomly reboot. 

Thanks!
