Bravura won't build on my Mac

[Harmonybear]

Greetings - I downloaded Packages and the Bravura Font Family.pkgpro file. It loaded into Packages and the file structure looks correct. But it won't build. Here's where it breaks: "Assemble payload files / Unable to copy item at path "/Users/redist/bravura-text.md" because the item could not be found. I don't understand from this message what the item even is. Any help is appreciated!

2017 iMac running Ventura 13.6.3

Thanks,

Gary
