thats work normally. I always use it for release

windeployqt.exe C:\Users\B\Desktop\Projects\MyApp\build\MyApp\

worked : (windeployqt6.exe C:\Users\B\Desktop\Projects\MyApp\build\MyApp\MyApp.exe)

What is the different windeployqt.exe and windeployqt6.exe ?

also

windeployqt.exe --webenginecore C:\Users\B\Desktop\Projects\MyApp\build\MyApp\

//or

windeployqt.exe --webenginewidgets C:\Users\B\Desktop\Projects\MyApp\build\MyApp\

working

QtWebEngine (based on Chromium) is not satisfied with the DLL itself: it also needs QtWebEngineProcess.exe, resources.pak/icudtl.dat files, and the translations/qtwebengine_locales folder alongside it. When they are missing, the renderer/GPU sub-process does not start correctly, and this manifests itself precisely as an access violation (0xc0000005) in Qt6WebEngineCore.dll at a variable time — not necessarily on the first run but at the point where the render is performed.

My old topic

I found the crash problem. WhenI write that topic, I think problem from socket, but I know now, problem is qwebengine.

@jsulm said in WebEngineCore crashes always:

Try a more recent Qt version.

Can it solve the problem ?

Try a more recent Qt version.
