I just wanted to create my own project and run these commands in order. When I ran west update command got the error below:

a.	cd C:\\
b.	python -m venv zephyrproject\.venv
c.	zephyrproject\.venv\Scripts\activate.bat
d.	cd zephyrproject
e.	west init -m https://github.com/zsen/sdk-custom-zephyrproject
f.	west update

(.venv) C:\zephyrproject>west update

Ok I found the issue because of:

I had a defined (but actually script file does not exist) west-commands in C:\zephyrproject\custum-sdk\scripts\west-commands.yml.
So When I removed them from west-cmd.yml file and then ran west update again. that worked for me.
