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?

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.

I downgrade. deleted "/Applications/Nordic\ Semiconductor" and reinstalled nRF Connect Command Line Tools version 10.24.0 and everything started working.

Hi Abhijith, This is resolved as of now. Still using the 10.23.5 tools. Had to restart the mac one time, and the board many times to get it to work. Not really sure what fixed it exactly. Mac OS version is 12.7.1 (21G920). Board is a 9160 based custom board using a Jlink EDU in this case.
I will try your suggestions if it becomes a problem again.
Here is the log again - /cfs-file/__key/communityserver-discussions-components-files/4/6242.log.log

Thank you

Hello,

I am unable to access the log file you shared. Could you try using the insert tab to paste the log? Also, please share which OS X version you are using. Is this a development kit or a 9160-based custom board? Additionally, could you try using a different version of the nRF command line tools? I recommend a version earlier than 10.17, as there are known issues with Mac and nrfjprog versions later than 10.17. Please give it a try and let me know the outcome.

Kind regards,

Abhijith
