看起来 FairyGUI 框架在 2-3 年前收到了相关 Spine 部分的最后更新。 因此，我认为它不支持最新的 Spine 版本，例如 4.1。
您可以询问 FairyGUI 框架的作者他们是否有计划支持更新的 Spine 版本。 或者，您需要使用旧版本的 Spine 编辑器（4.0 或 3.8）并重新导出您的资产。
It looks as if the FairyGUI framework has received it's last update to the relevant Spine parts 2-3 years ago. As a result, I would assume that it does not support the latest Spine versions such as 4.1.
You could ask the authors of the FairyGUI framework whether they have plans to support newer Spine versions. Alternatively you would need to use an older version of the Spine Editor (4.0 or 3.8) and re-export your assets.
