从直接c#和jslib回调c调用事件时，会调用不同的函数签名#

我正在从事一个Unity项目，处理WebGL插件，Unity称之为“jslib”

虽然unity建议在jslib与c#交互时使用UnitySendMessage，但我更喜欢使用委托作为回调。在一个小的测试代码中，它起了作用。但当它运行到触发事件代码时，会发生奇怪的错误

c#：

调用UserLoginDispatcher中的ProcessLoginOver时，测试中的onLoginOver会抛出错误：

使用签名“viiii”调用的函数指针无效。可能这是一个无效值（例如，对空指针调用虚拟方法导致）？或者调用类型不正确的函数会失败？（值得使用-Werror构建源文件（警告是错误），因为警告可能表示可能导致此问题的未定义行为）

但如果我尝试直接用c#代码调用此事件，它可以成功触发

错误调用堆栈：
