A weird thing. I have a MacBook Pro 16 inch M1. It has one of those flush SD cards (1TB) that I keep in there permanently as scratch space. Everything worked fine before the 13.4 update. 

Pre-13.4, on a reboot, the card would show up like normally. But now, with 13.4, the card will not show up after a reboot or power off/on. I have to remove, then re-insert the card. Then its fine and I could remove and reinsert the card all day, no issue. It just doens't show up on intial reboot. As I said, it was fine before 13.4. I even ran diags just to make sure, and no issues were found.

Bug? Anyone else see this?
