Issue:
I would like to bring to your attention that I am getting an error when running the 'list command using the nrfcredstore cli utility, while trying to retrieve the flashed credentials on my nrf9151 DK. The following error appears:

What I've done:
As expected, I have flashed the device with the at_client sample application.
I have verified I can retrieve a list of the keys from the device when I manually enter the AT command :
AT%CMNG=1
I have tried multiple version of the tool chain and I seem to get the same error.

I have also tried to power cycle the device of course, with no luck. I have also tried a seperate nrf9151DK board, and face the same issue.
I want to add that I have flashed multiple sets of credentials on this device, and thus I suspect this may be contribuing to the issue as I have more than the standard two sets of credentials and associated security tags, on this device.
I would also like to mention that I am still learning the NCS toolchain and associated usage. Yesterday the nrfcredstore cli command worked, but today I have git fetched and git pull origin main in the 'nrf' repo inside the ncs parent directory. I proceeded to run 'west update' as instructed online. I have noticed I have the most recent commits (I can see this by viewing the logs), but I am not sure if I am supposed to have new toolchain 'hash' or whatnot. On this note I would greatly appreciate some clarification as to how the toolchains , located in the 'ncs/toolchains/ <hash_here> ' directory, are dependant on - or related to- the current commit I am in on the main branch of the nrf repo.
Dev setup:
OS: Linux Ubuntu 24.04.1
nrf9151DK HW v0.9.0
