Unable to create bundle at URL (<private>): unable to create file system representation of URL (13)

We use network extension for the VPN connection implementation. In the network extension, we need to call a third-party library to do some check. Before the macOS is upgraded to 15.2, everything is fine. It just stop working after macOS is upgraded to 15.2.

I did some debugging, and looks like the api provided by the dylibs is blocked. One system log is shown suspiciously

The background is that we did embed the third-party dylibs in the app resources folder and the app extension tries to dlopen the dylibs and call the functions. And actually we do not know how the dylibs are implemented. Since it was working with older macOS, we would like to see if there is any related change on os itself.

I have tried to change the places of dylibs, moving them from container app bundle resource folder to app extension resources folder, even the app group folder. Unfortunately it does not work either.

Do you guys have any opinions?
