I've experienced the same issue. I took our 2020 Model Y to service last week. They replaced the driving computer (for other errors) and the "USB Hub". It was working when I picked it up. But it stopped working again a few days ago (likely after I upgraded to 2023 based version of V12). I tried a reset and that didn't work but it seemed to trigger enough change that it prompted me to reinsert the USB (micro SD in a USB adapter). That made it recognize the drive and I got it going again.
The car had reverted to older version of the software after the driving computer replacement. Last night I finally got 2024.3.10 (again). What was interesting was the car had 2024.3.10 when I took it in for service and I had been unable to reproduce the issue with the software. It seemed to me the problem started with an earlier version of V12 FSD.
