My installed banks won't open in komplete kontrol 3.4.1

I lose hope, everything was reinstalled cleanly, the banks opened correctly, and the message came through again:

I've rescanned my plugins but Kontakt 8 doesn't want to be scanned. Is there any way other than having to uninstall everything again to force Kontakt 8 to scan?

JI had to manually add KK K8 and Reaktor to full disk access, reboot, then open each of them. Only Reaktor asked me to authorize access to the local disk.

And when I go to the local disk, KK K8 are not present, when opening, I never got the message telling me to accept this.

Is there a “local” way on my computer to force access because, even with clean uninstalling and reinstalling, I find myself at a dead end. For K8.VST3 in KK, here is the missing:

I spent the day reinstalling everything after rebooting my system. I just want to keep writing music.

Hi NI team,

Yesterday, I performed a complete erase and clean reinstall of macOS (Sequoia 15.4.1) to start fresh and try solving the persistent “Plug-in not found” issue in Komplete Kontrol.

Here’s a detailed breakdown of what happened:

1. Initial Reinstall:I freshly reinstalled Native Access, Kontakt, and Komplete Kontrol only.→ Everything worked.→ Komplete Kontrol could scan Kontakt correctly.→ Full Disk Access and Local Network Access permissions were granted and visible.
2. Plugin Reinstallation:During the day, I reinstalled all my VST3 plugins (including some non-NI and some older ones).Later, I initiated a rescan in Komplete Kontrol.
3. "Plug-in not found. Loading issue plugins/preset could not be loaded, as it does not yet support Apple Silicon or VST2/VST3."
4. Then I rebooted and reinstalled everything via Native Access.
   • /Applications
   • /Library/Application Support
   • ~/Library/Application Support
   • ~/Library/Preferences
   • /Library/Audio/Plug-Ins/VST3
   • ~/Documents
   • Hidden Library files including NIHardwareAgent, NIHostIntegrationAgent, and NTKDaemon
5. Reinstall failed to restore previous state:
   • The system extensions NIHardwareAgent, NIHostIntegrationAgent, and NTKDaemon appeared as blank/generic files, not functioning correctly.
   • I removed them again and reinstalled them properly, then manually granted Full Disk Access.
   • However, this time Local Network Access was no longer visible or granted, even after launching the apps again.
6. Kontakt and Massive stopped appearing in scans, and the same error message persisted.

❗ My questions:

• Could Local Network Access be granted only once, during the very first execution of the app?
• Is it possible that some scanned plugins that are not fully Apple Silicon (ARM) compatible could corrupt the scan process or prevent proper reinitialization of access rights?
• Should I consider creating a dedicated folder for these incompatible or legacy plugins and exclude it from Komplete Kontrol's scan path to prevent issues?

This issue is now 100% reproducible on my setup, and I strongly suspect a conflict between Sequoia’s tightened privacy policies and plugin-level compatibility.

Happy to provide logs, diagnostics, or collaborate on deeper testing.

Thanks for your time,— Hugo
