Spreadsheet extension doesn't work.
I downloaded this Spreadsheet Extensio
https://github.com/Naninovel/Spreadsheet
from here
https://naninovel.com/guide/spreadsheet ... stallation
and i imported Naninovel from assetstore.
But when i build this project I faced this error message.

My Unity3d version is 2019.4.40f1 Personal.
Is this example project something wrong?
Thank you.
