nrfjprog throwing erros

[Aaron]

I have been using visual studio code on mac for development, and it started showing error code 63 when I try to start debugging on the 9160 based hardware. It used to work okay few days back.

To see more details , I tried running the nrfjprog directly on command line:
------

# nrfjprog --program /Users/admin/NordicProjects/asset_tracker_v2/build/zephyr/merged.hex --sectorerase --verify -f NRF91 --snr 801042885 

[error] [    nRF] - Exception encountered while attempting to initialize multiprocess client: Operation not permitted

ERROR: An internal error has occurred, please try again.

NOTE: For additional output, try running again with logging enabled (--log).

NOTE: Any generated log error messages will be displayed.

# nrfjprog --program /Users/admin/NordicProjects/asset_tracker_v2/build/zephyr/merged.hex --sectorerase --verify -f NRF91 --snr 801042885 --log

[error] [    nRF] - Exception encountered while attempting to initialize multiprocess client: Operation not permitted

ERROR: An internal error has occurred, please try again.

----------------
Tried installing version 10.23.5 tools for macOS, and still errors out but with a differnet message.

# nrfjprog --program /Users/admin/NordicProjects/asset_tracker_v2/build/zephyr/merged.hex --sectorerase --verify -f NRF91 --snr 801042885 --log

 Any guess what is going on?

Hi, like others here I had to down grade nRF Connect Command Line Tools  to version 10.24.0 to get this working.

I have a Mac book air M3 with MacOs 15.3.2

Really annoying bug that should be fixed.

Hi Everyone !
I tried doing as you guys said above. I downgraded the nrf command line tools 10.24.0 .But it doesn't seem to work either
Do we have any more effective solutions to handle this error?
