Webengine crashing on Rhel9

The renderer process crashes in RHEL9 when sandboxing is enabled (sandbox is enabled by default)

Repro:

• Build Qt provided Webui example (https://doc-snapshots.qt.io/qt6-dev/qtwebengine-webenginewidgets-webui-example.html)
  • note: we had to use google linker adding the following line QMAKE_LFLAGS += -fuse-ld=gold to the provided pro file, otherwise we were getting linker errors

• Run the produced webui application
  • The displayed webui page will be completely blank
  • listing the webui processes (ps -ef | grep -i webui) we can notice that the process  QtWebEngineProcess --type=renderer is missing (dead or not started)
