UNUserNotificationCenter crash (bundleProxyForCurrentProcess is nil: mainBundle.bundleUR)

This is a duplicate of a question I already asked (https://developer.apple.com/forums/thread/133303?login=true), but I wanted to edit its tags, and I couldn't do it, so I'm asking again:

I've implemented a VPN app for iOS and macOS using Packet Tunnel Provider.

I released a macOS testing version for our QA (development distribution).
On two different Macs the app works great, but on a third Mac, the app crashes when the extension tries to send local messages using UNUserNotificationCenter.
The user chose (at the containing app) to not allow the app to send local notifications.
At the extension, I'm trying to send a notification, but AFAIK this code should do nothing if the user didn't allow it. But it shouldn't crash the app.

This is the exception:

• Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'bundleProxyForCurrentProcess is nil: mainBundle.bundleURL

And those are the logs from the Console:
