If you can mail me your original and compiled zipfiles, I can try asking the makers of the game.
But generally speaking, you're a bit on your own with the Unity version: it's meant for advanced users only
Viewing post in CSV loading issue
Yeah, fair point: remember that the Unity version still needs the CSV file. It is the very same build as the "normal" version after all!
And while I'm here, another pointer: the game is only tested to run on Itch.io
Other servers might have setting that affect its functions, and it will be up to you to figure those out
(= if you decide to use your own server to speed up things, cool for you but don't ask us here. You're on your own...)
