我在将Mac catalyst应用程序分发给测试人员时遇到问题，当它在我的机器上正常运行时，在其他机器上启动后立即崩溃，没有任何人类可以理解的崩溃报告。
此外，当我们用Xcode在mac上运行它时，它正常工作，当它被运到我的mac时会崩溃。这里我做了什么-我使用的是Xcode 11.3.1，申请是自动签署的，我在发货前公证了它，没有错误。
有人知道它为什么会崩溃吗？

经过长时间的研究，我发现了这个问题。我们在应用程序中使用了自定义字体，导致了崩溃，这似乎是苹果的错误，因为字体链接正确，并添加到了Info.plist中。此外，在安装了字体的机器上，应用程序没有崩溃。将字体更改为苹果提供的类似字体后，该应用程序可以完美工作。
