Onstar Module Replacement ETA?

I have become one of the casualties of the Onstar Module.  I booked an appointment at my GMC dealership for an oil change and recall software update to my 2022 GMC Sierra Denali 1500.  Several days before my appointment, I noted my truck connectivity via the Onstar system had stopped.  The dealer noted the issue and began the oil change and the software update.  Apparently during the software update,  the ability of the computer system not to be able to communicate with the Onstar Module made the truck computer system that deals with all the safety systems, four wheel drive, etc., to illuminate all dash warning lights and many of the systems to stop functioning.  The dealer informed me they believe the problem can be corrected with a new Onstar Module.  However, there is no ETA on a replacement.  My truck is now un-usable and sitting at the dealership.  What is being done to solve this repair part problem?
