There's an old comment in the code which makes me think you bumped into this problem:

psutil/psutil/_psutil_windows.c

Line 544 in ac0da3f

// May fail any of several ReadProcessMemory calls etc. and

Unfortunately I don't know how to fix it. ProcessExporer may be able to correctly determine the cmdline because it uses a driver whereas psutil doesn't.

It looks like this was already tracked as of 6 years old #56.

Note: this may have been fixed recently with the introduction of Process.environ as that part of the code has been rewritten. I would like to know what happens when 4.0.0 is out (unless you can compile psutil).

OK, I confirm it looks the old logic ignoring the error and returning an empty list is gone, see:

psutil/psutil/arch/windows/process_info.c

Line 703 in d4a0717

psutil_get_cmdline(long pid) {

Closing this out.
