WebEngine application do not work as standalone

[filipdns]

Hi guys,

I'm trying to run the Qt WebView application on Windows 7. It works perfectly for me run with Qt Creator 4.7.2 but when I deploy the application on windows with windeplyoqt and copy libssl-1_1-x64.dll and libcrypto-1_1-x64.dll on app directory . There is no error, the app just closes immediately after starting.
I am using the MSVC2017 64bit Desktop Kit and Qt 5.14. Are there any known issues for Webview / Webengine on Windows?

windeployqt.exe --qmldir "E:\webEngineApp" "E:\AffichageMeteo\Info.exe"

Trying in debug mode I received:

I hope you can help me.
