Coding Help Change Spritefont (XNB)

[yustar]

I'm using Monogame framework and Visual Studio for Mac to compile Arial spritefont to XNB format by following this tutorial: https://docs.monogame.net/articles/content/adding_ttf_fonts.html.

Everything seem to be OK, but when I use Content Patcher to patch, the game couldn't load new font and throw following error.

Hope someone could help me with this problem.
