"Resource entry already has bag item" error when re-encoding TikTok

[axel578]

When I try to use your tool for tiktok it says that :

  ↓ Disabling certificate pinning [skipped]
    → No certificate pinning logic found.
  > Encoding patched APK file
    ↓ Encoding using AAPT2 [skipped]
      → Failed, falling back to AAPT...
    × Encoding using AAPT [fallback]
      → I: Building resources...
    Signing patched APK file

   Failed!  An error occurred:
