使用GitHub Action通过Buildozer构建APK失败求助

我基于Kivy框架开发了一款Yamb游戏，代码在电脑PyCharm和安卓手机Pydroid3中均可正常运行。本地用Buildozer生成APK时遇到环境安装问题，于是改用GitHub Action直接构建，本以为流程差不多，但改了buildozer.spec里的依赖、文件等所有能想到的配置，还是始终卡在同一个错误上（错误详情如下）。

仓库已设为公开，地址：https://github.com/SegiMan/Yamb/tree/main

我刚从Tkinter转用Kivy和面向对象编程，希望有人能指出问题所在，万分感谢。
