we have an app that renders some off-line files via QtWebEngine. The app is multiplatform. Yet recently when upgrading to Qt6 on MacOS the rendering stopped working.
If I turn of the QtWebEngine sandboxing, it works. The app does not use apple sandboxing.
I run out of ideas how to debug what is wrong.
I run all kinds of debug outputs.
I get
sandbox initialization failed: empty subpath pattern?
Is there something that changed from Qt5-Qt6? How to debug this? Or how to have non-empty subpath pattern?
I have the same situation.pyqt6.5.0, pyinstaller5.1 My windows is OK. But my mac(both m1 and intel) both not. When I add os.environ['QTWEBENGINE_DISABLE_SANDBOX']='1' my program will log malloc: Incorrect checksum for freed object 0x1538c0bc0: probably modified after being freed. malloc: *** set a breakpoint in malloc_error_break to debug
when I do not the screen will blank and show sandbox initialization failed: empty subpath pattern sandbox initialization failed: empty subpath pattern
I don't know how to fix it
