I hope to know the cause of this phenomenon and get help to solve this problem.
.NET Framework 4.6.2
CefSharp 109.1.110.0

我猜测，我的情况可能是这样造成的。
1、我原来有一个form上用的别的浏览器控件
2、后来我把他换掉了，但是我没有在from上编辑，我直接修改了Designer.cs中使用的类
3、没有注意查看界面是否能正常打开就使用了。

经查，在Designer.cs文件中有不属于cef浏览器的属性，但是他居然编译通过了。
我去掉了不正确属性调用，from也可以正常查看了。运行时没有在发现有这种中断点到达的提示。
尚需继续观察，不是所有用户系统都可以复现这个情况，只有个别两个人有这个崩溃情况。
