android-perf-testing Windows - Error running systrace: close_fds is not supported on Windows platforms if you redirect stdin/stdout/stderr

This happens when I try to run the command given in Step 5:

python %ANDROID_HOME%/platform-tools/systrace/systrace.py --time=10 -o %userprofile%/trace.html gfx view res

Full stacktrace:

Any hint on how to solve this?

Addendum: It's working when run from Android Studio's device monitor.
