No output file after attempted conversions

(Based on prior email discussion, migrated to this issue)

I am looking to convert a 研究社 Yomichan dictionary for potential use with my Kobo. However, I've run into some difficulties.

cargo run kobo_jp_dict -y 研究社　新和英大辞典　第５版.zip dicthtml-ja-en.zip

On running this command in Cygwin, I am met with the following error:

cargo run kobo_jp_dict -y 研究社　新和英大辞典　第５版.zip

On running this command, I am met with:

Unlike with the first command, which I based on the example in the readme, this one seems to work(?) in that the program appears to spend roughly 3 minutes doing something—however, at the end of the process, there doesn't seem to be an output file anywhere.

By sorting files by Date Modified in Everything, I'm able to see files such as MARISA-BUILD.EXE-908E7366.pf and KOBO_JP_DICT.EXE-CF27C84A.pf appearing/being accessed while the command is running, which implies to me that the program itself and Marisa are functioning throughout. Whether or not as intended, I'm not sure.

Attempts at troubleshooting so far:

Putting quote marks around 研究社　新和英大辞典　第５版.zip — Yields the same result, that is, no output file
Trying the process with jmdict_english.zip instead — Same result, no output file

For reference, here are what my file paths look like, in case that might help: (Sorry for the image wall, not sure what will and won't be useful.)

Any and all guidance would be appreciated. Thank you for your time.
