"Imported library contains no keywords"

I’m putting this here because I cannot find a RemoteSwingLibrary forum. Nevertheless, the issue presents with multiple libraries. I suspect it’s an installation issue. I looked at PYTHONPATH and everything seems fine, which means something is usually wrong.

I’m running Python 3.9, Jython 2.7.2 and RF 4.1.dev1 on a standalone Windows Server 2019 VM, so getting this far has been a challenge. Looking for possible solutions or suggestion for what to try next.

Thanks!
