Check, whether the firmware file is exported correctly, and in correct size.
Apparently, the auto-remounting side effect of the v0.46 change, is disturbing the export process.
Unmounting the UV just before the export gives the device 20/20 success rate.
Test case for issue https://github.com/Nitrokey/nitrokey-app/issues/399
