Error running build - 'derived' is not recognized

[NHLOCAL]

Description

I'm trying to build a Windows app using the builtin command, but I'm getting a number of errors at the icon creation stage
The error also exists when I try to run the command on the example directory that can be created with the create command

Code example to reproduce the issue:

flet build windows gui-project
