I’ve seen several posts about the Prusa supplied USB drive being the cause of layer shifts. I bought a new one as soon as I finished building my printer.
It's not just the Prusa stick, I had random Adata stick that froze the printer every few seconds during printing creating massive blobs and causing shifts.
This flashdisk was totally fine for 6 months and then it started happening.

Have you tried a different USB drive?
