When in the SCCM 2012 console under Software Updates, I click Deploy on a Software Update Group and the console hangs indefinitely. It just stops; I click away and back and Windows does not recognize that the console has stopped responding. I end up having to kill the console through Task Manager. I have left the console for hours and it never becomes responsive again.

I have tried removing and reinstalling the SUP, without success. Server reboots do not help, either. The issue with the console occurs both on my desktop, and directly on the site server itself.

Any ideas? I've checked server logs and found nothing that would be indicative of a problem.

Update: I managed to find something from the SMSAdminUI.log file:
