Calling rflint with argumentfile succeeds but rflint is not actually run

[pfctdayelise]

Using RF 3.2.1 with Python 3.8.1 on Windows 10, rflint 1.1

Not sure what I am missing here. rflint accepts my argumentfile but doesn't seem to actually run rflint. If I run rflint with the arguments manually inserted, I get output (ie lint errors), but with the argumentfile I don't get any output.

(.venv) PS C:\Users\bjl\Workspace\robot-framework-skeleton> cat .\rflint.txt
--verbose
--recursive
tests
(.venv) PS C:\Users\bjl\Workspace\robot-framework-skeleton> rflint --verbose --recursive tests
