unstoppable "System Extension Error" after update to Sonoma 14.6.1

After updating my macbook air M2 to latest sonoma version (14.6.1), I get "System Extension error" at startup, after going to privacy and security setting it says: "some system software requires your attention"

after clicking "Details", It says: "system software from the following developers was updated and the system needs to be restarted before it can be used."


Listed names are "Apple Inc-Updated / Motu-Updated", then I Click on OK and after putting my password and choosing to restart, System Restarts.


after loading , I Recieve the exact "System Extension error" Again, Like Nothing has changed! Everything is just like before and again it needs to restart. I did it again and again and no change at all.


Now my mac doesn' t recognise my soundcard (Ultralite MK3 Hybrid)


before this update my OS was a lower version (14.0) of Sonoma And everything was working nicely.


what fixes or workarounds I've already tried:


1. from Startup Options I Select “Reduced Security” and enable “Allow user management of kernel extensions from identified developers” to allow installation of software that uses legacy kernel extensions.

2.uninstall and remove all drivers and installed it again with the latest version that is availabe in website, the one was installed before and was working fine.

3. Repair startup disk with First Aid

4. disconnect second monitor and disable any mouse or touchpad assistant to adjust privacy settings.

5. do all the thing that mentioned above with and without connecting soundcard.

6. remove motu .kext files from library, restart, to Solve "apple Inc-Update", then after restart the error was gone, after that install motu driver, restart, recieve Error and "Apple Inc-Updated / Motu-Updated" is there again.

MacBook Air, macOS 14.6

Everyone: You are not permitted to discuss the macOS 15.x Sequoia beta software anywhere except in direct communication with Apple through the Beta feedback app. You agreed to these terms when you downloaded & installed the Beta software. Here is a bit from the Beta FAQ from here (about 7 items down the page...I've added emphasis to the quote):


Apple Beta — FAQ

Is the beta software confidential?

Yes, the beta software is Apple confidential information. Don’t install the beta software on any systems you don’t directly control or that you share with others. Don’t blog, post screenshots, tweet, or publicly post information about the beta software, and don’t discuss the beta software with or demonstrate it to others who are not in the Apple Beta Software Program.
