(! status in pluginkit, FinderSyncExtensionHost process missing)

macOS Version: 26.3.1 Beta (25D771280a) Xcode Version: 16.3 (17C529)

Steps to reproduce:

  1. Create a Finder Sync Extension project
  2. Build and install to /Applications
  3. Enable in System Settings → Extensions → Finder Extensions
  4. Extension shows ! in pluginkit output
  5. FinderSyncExtensionHost process never starts
  6. Context menu never appears in Finder

Expected: Extension loads and context menu appears Actual: Extension marked with ! in pluginkit, no process launched

pluginkit output: ! com.github.astronautJack.EasyNewFile.EasyNewFileExtension(1.0)
