I noticed this yesterday (2023-06-14) - I built and flashed firmware from rustc 1.70 and the firmware failed to start up and enumerate as a USB device.
I haven't investigated the exact cause yet, or where it's crashing.
I also haven't identified the exact point in rustc versioning where it fails to work, but I can confirm that rustc 1.60 does not exhibit this behavior.
