    This canonical solution was verified and marked as solved in the Apple Support Community archive.

    Reinstalling Rosetta 2 runtime daemon and rebuilding LaunchServices database.

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

    1. Force reinstall Rosetta 2: 
      softwareupdate --install-rosetta --agree-to-license
    2. Reset LaunchServices database: 
      /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user
    3. Kill daemon to rebuild fresh cache: 
      sudo killall -9 oahd

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