Cmake Error While Building Blinky Sample



I am trying to west build the blinky sample from the getting started guide ( However, the below error comes up:

C:\zephyrproject\zephyr>west build -p auto -b nrf52840dk_nrf52840 samples\basic\blinky
-- west build: generating a build system
Including boilerplate (Zephyr base (cached)): C:/zephyrproject/zephyr/cmake/app/boilerplate.cmake

I have tried restarting my pc, and checked the GNU ARM Embedded toolchain installation and that the environment variables were set correctly. I have also checked that the cmake folder exists in the zephyrproject and I tried reinstalling the cmake packages. Still the same error keeps occurring.

Any help with diagnosing and fixing this issue would be greatly appreciated.
