I give up. I ordered a Mac Studio that’s set to be delivered May 30 - June 6. I just can’t stand the idea of what repeated, random shutdowns are doing to my data. I’m basically paying $$$ for Apple to be more responsive to any problems with the Mac Studio since they seem to have all but lost interest in solving this Mac Pro 6,1 issue.
The trashcan is being retired to bookshelf decoration duty just as the new new Mac Pro is likely to be announced at WWDC.

Since you're at your wits end and have already ordered the Studio, you have nothing to lose by upgrading the firmware. Who knows, you might even cancel your order.
