Has LR 12.1 broken tethered capture - Apple Silicon with Nikon Z6

Tethered capture used to work. I'd start tethered capture, restart in Rosetta mode, start it again, and then photograph away. Now, the "Detecting Camera" dialog box just sits there spinning away.

This worked on the previous version of LR Classic.

Thanks

Camera: Nikon Z6. Firmware 3.50 (also did not work on 3.40).
