@Joe-von-Habsburg Use a debugger to get stack trace.
Try a more recent Qt version. -
I cant receive crash on debug mode,
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 ?

You run the exe directly from build\Desktop_Qt_6_9_3_MSVC2022_64bit-Release, i.e. from a raw Qt Creator build folder — not from a build that has been windeployqt. 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.

Run windeployqt.exe --webengine on your exe (from C:\Qt\6.9.3\msvc2022_64\bin), and check again if the crashes disappear.
