P1: Critical Description
Note: this issue may be a duplicate of QTBUG-95459, but as the stacktrace is different, and the existing ticket is closed, I prefer to create a new one.
When I start the "Minimal WebEngine example" on Windows/Debug with Qt 6.2.0. beta3, the program crashes. The issue doesn't happen on release build (maybe because assertions are disabled).
The issue was reproduced on two distinct computers.
Same issue happens with other WebEngine examples (Google maps....)
This problem prevents me from launching my application in debug mode, because it starts with a web login.
Here is the stack trace:
