Nordic has a range of microcontroller families. They specialize in low-power Bluetooth MCUs, and their portfolio includes the nRF52, nRF53 and nRF92 range of MCUs (they call them SOCs).

The nRF5 SDK entered maintenance mode around the year 2021-2022¹, with the intention that new FW projects would use the Nordic nRF Connect SDK instead.

PS C:\Users\geoff> nrfjprog --program C:\my_file.zip --verify
[ #################### ]   0.000s | Finding image components - Finished
[error] [ Client] - Encountered error -93: Command program_file executed for 79 milliseconds with result -93

ERROR: Access to the selected address is blocked by the SPU.

The problem in my case was an old version of nrfjprog. After upgrading from version 10.21.0 to 10.24.2, the above error was resolved.

Before upgrading:

PS C:\Users\geoff> nrfjprog --version
nrfjprog version: 10.21.0 external
JLinkARM.dll version: 7.94e

And after upgrading to 10.24.2:

PS C:\Users\geoff> nrfjprog --version
nrfjprog version: 10.24.2 external
JLinkARM.dll version: 7.94e
