Hi there guys. After hours of searching the net about why my program was crashing I finally found a thread that says you can't use QWebEnginePage in a console app without changing QCoreApplication to QApplication, so I did that and that solved the crashing problem. My program is multi-threaded and the QWebEnginePage object runs on one of the threads. Now, when I run the program I get the attached error in my console output.thread_error.jpg How can I resolve this?
