"undefined path" when opening the theme file dialog

I'm using the v7.1.5 build on Windows 10. This is the stack trace:

internal/fs/utils.js:426
Uncaught TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be one of type string, Buffer, or URL. Received type undefined

Repro: Open the "Open Theme" dialog.
