Flushing AudioUnit cache plist and triggering an isolated AU validation pass.

Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

  1. Quit Logic Pro and delete the corrupt cache: 
    rm -f ~/Library/Caches/AudioUnitCache/com.apple.audiounits.cache
  2. Kill core audio daemon: 
    sudo killall -9 coreaudiod
  3. Open Logic Pro, navigate to Settings > Plug-in Manager, locate the crashed AU plugin, and click Reset & Rescan Selection.

Following this procedure restores full stability with zero recurring log errors.
