Listary Portable giving FlaUI.Core error

When Listary launches, we get following error and the app crashes. Direct app installation and running doesn't have this issue, it only happens when launching through portableapps launcher. Seems like it's unable to load FlaUI.Core, but I can see the DLL file is available in the "Files" folder under plugins. Can some provide guidance on how we can fix this?

Listary has encountered a problem, please restart it.
