OSX ARM: Webpage does not show

On run time when a webapge is being open, for some reason it is not showing anything. This is happening on ARM (M2) machine on osx 15.0 

It looks like in log webengine initialization seems not to appear .
The same Qt build, used using Assistant.app shows no issue.
The Qt version built on macOS x86 (with same parameters) shows no issue.
I could get the webpage to show as expected by setting QTWEBENGINE_CHROMIUM_FLAGS="--single-process"

Attached are two logs:Logs are used by adding this to the run-time environment:
export QT_LOGGING_RULES="qt.webenginecontext.debug=true"
export QTWEBENGINE_CHROMIUM_FLAGS="--enable-logging --log-level=0 --v=0 --single-process"

Also attached is one patch which seems to fix the issue. 

Qt's simple Browser example seems to be working fine. Unfortunately we do not have any reproducer at this moment. But since the attached patch seems to work. Can you please have a look of it and see a potential flaw or even better solution?
