Is it a problem on my end somehow?

This should be fixed after #7, which should also render it unnecessary to pass empty --editor-args for neovim as I suggested in your closed issue #5. I believe this warrants a minor release to pypi to ensure non-vim users can benefit from these changes. Thanks a lot for helping me improve this interface!

[MFreidank]

Update: the pypi release is out, if you execute: pip install --upgrade ankivim it should pull the new version that should handle these cases much more gracefully. Thanks again, if you encounter any additional issue, feel free to open an issue again.
