Hi,
We are facing a crash while a QtWebEngine window is created inside an executable that runs as startup app. It crashed both Windows 10 and 11.
This is a sample application to trigger the error
#include <QtWidgets> #include <QtWebEngineWidgets> #include <qtwebenginewidgetsglobal.h> int main(int argc, char * argv[]) { QApplication app(argc, argv); QMainWindow *browser = new QMainWindow(); QWebEngineView *view = new QWebEngineView(browser); view->load(QUrl("https://www.google.com")); browser->setCentralWidget(view); browser->resize(1024, 768); browser->show(); return app.exec(); }
And this is the exception collected by the command fired as soon Windows is available
"Procdump.exe" -ma -e -t -w sample.exe

Is related with #QDS-15693 but the bug was closed because QDS stopped using QtWebEngine
Steps to obtain a dump for boot apps:
- Create example project called sample, compile and windeployqt
- Download procdump from Microsoft
- Create a sampledump.bat file in Desktop for quick access with "Procdump.exe" -ma -e -t -w sample.exe
- In Registry create inside "Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" a new key with the absolute path to the example project exe
- Log out of windows (or restart)
- Log in and double click sampledump.bat file as soon UI is available
- Procdump will log the crash and will create a dmp file
We tried to start procdump using registry but was not working properly so double click in Desktop worked
Thank you in advance
