I am building a Swift Package via Github Action, which was working fine previously, the only change I did in a package is added custom font files in Resources folder,

            resources: [
                .copy("Resources/Fonts")
            ],

These changes were merged into the branch, and now have started getting the failure logs as mentioned below for the Github Action,

Based on the solution have made the scheme related changes in a temp branch, and Github Action built the package, but I am not clear why font file is causing scheme related issues.
