Greetings, KARR, DAVID!

There's no need for it, if you are ready to trade some headache for
convenience.
Just use your profile as your Cygwin $HOME.

>     error: CreateFile C:\cygwin64\home\<userid>\.kube\config: The file cannot be accessed by the system.

> That path is my CYGWIN home, where in that directory I have this:

>     % ls -lt .kube
>     lrwxrwxrwx 1 <userid> Domain Users 22 Aug  8  2024 .kube -> /c/users/<userid>/.kube//

The question stands, WHAT is that symlink?

>>      cmd /C dir .kube

> So the kubectl exe, which is a Windows application, seems like it is

Generally, it is a bad idea to use two tools of different origin for the same
purpose. I suggest you write a simple wrapper to use windows one in Cygwin.

Smth. along the lines of

>> #!/bin/sh
>>
>> (
>>     _cmd=
>>     if [ "$1" ] && [ -f "${_cmd:="$( cygpath -aml -- "$1" )"}" ]; then
>>         shift
>>         set -- "$_cmd" "$@"
>>     fi
>>     unset _cmd
>>
>>     eval "PATH='/proc/cygdrive/C/Program Files/nodejs:$PATH'" export PATH
>>     "/proc/cygdrive/C/Program Files/nodejs/npm.cmd" "$@"
>> )

> Not sure if I’ll ever figure out what’s really happening here, but at least I have a solution. Thanks.
