Unable to Flash Blinky Sketch

[Tanmoy]

Using Visual Studio Code as IDE with installed nrf SDK v2.9.0 on MacOS Sequoia 15.2

Terminal reads - 

* Executing task: nRF Connect: Build: blinky/blinky (active)

Building blinky
west build --build-dir /Users/<UserID>/nrfworkspace/blinky/build_1/blinky /Users/<UserID>/nrfworkspace/blinky

ninja: no work to do.

Flashing blinky to Blooper
west flash -d /Users/<UserID>/nrfworkspace/blinky/build_1/blinky --skip-rebuild --dev-id XXXXXXXX --erase

-- west flash: using runner nrfutil

How to get around this ?

Hello,

-- runners.nrfutil: Board with serial number XXXXXXXX flashed successfully.

This indicates that the board is flashed. Can you let me know if the blinky application is running or not on the DK?

Error: no such option: --json

Is the --json option listed when invoking "nrfutil -h" in an nRF Connect terminal? For example, the output I get for nrfutil v7.13.0 from the nRF Connect terminal in VS Code is below.

PS C:\ncs\v2.9.0> nrfutil -h
nrfutil 

Usage:
    nrfutil [+MODIFIER] [OPTIONS] [SUBCOMMAND]

      --detect-proxy             Invoke libproxy's 'proxy' utility program to retrieve proxy server info and use it
  -h, --help                     Print help (see more with '--help')

No, it seems the board finished flashing but the hex file is never actually uploaded. It seems to me that something is wrong here -
