My FinderSync Extension is blocked by the System

Hi guys,

I'm developing a FinderSync Extension that extends Finder contextual menu with a couple of items doing some trivial file operations.

I'm using Xcode 16.2 on macOS Sequoia 15.3.2

I could run the containing app in debug, and in System Preferences -> File Providers the flag is enabled for my app finder extension.

Anyway, the contextual menu does not show in Finder, probably because the finder extension crashes immediately.

Some output:

pluginkit -m | grep "com\.[^a]" 
+    com.mycompany.MyApp.MyAppFinderExtension(1.1.14)

The log is showing something very strange:

log show --predicate 'eventMessage contains "com.mycompany.MyApp" and messageType = error' --last 1h

Filtering the log data using "composedMessage CONTAINS "com.mycompany.MyApp" AND logType == 16"

Especially the first line: MyApp is not accessing coreaudiod - neither trying to get a ScreenCapture, so ... WTF???

How is it possibile? Why is the system blocking MyApp FinderExtension, or preventing it to run?

Thank you in advance
