My Mac Pro shipped with Catalina 10.5.1. I installed an ASUS M.2 PCIE add-in card with a Sabrent Rocket NVME SSD and everything was working fine. Formatted the Sabrent in Disk Utility as an APFS drive and was able to see it in Finder and Disk Utility.

Yesterday afternoon I decided to upgrade to Catalina 10.5.3 and after doing so, I was unable to see the Sabrent Rocket in either Finder or Disk Utility.

I figured I'd try rolling back to Catalina 10.5.1 with Time Machine. Everything seemed to go smoothly. However, now I can't even get to the desktop. As soon as I enter my password, I just get a continually spinning disk. There is no way to Shut Down the computer other than to hold down the power button. I restarted and it's been spinning for about 15 minutes now. I've been on hold waiting for Tech Support for a while now.

Anyone else run into this issue?
