使用webengine（例如，quicknanobrowser）运行示例之一时，项目以发布模式运行，但是尝试以调试模式运行时崩溃。
这是回溯，我进入qtcreator。
开始 D：\ Qt \ Examples \ Qt-5.11.0 \ webengine \ build-quicknanobrowser-Desktop_Qt_5_11_0_MSVC2017_64bit-Debug \ debug \ quicknanobrowser.exe ...
启用QML调试。仅在安全的环境中使用它。

程序意外完成。
该过程被强制结束。
D：/Qt/Examples/Qt-5.11.0/webengine/build-quicknanobrowser-Desktop_Qt_5_11_0_MSVC2017_64bit-Debug/debug/quicknanobrowser.exe 崩溃了。
任何人都知道发生了什么事吗？
