Possibly Google bug: [https://partnerissuetracker.corp.google.com/issues/255732500]

Wait for news there.

How to reproduce:
1. Open the user’s attached “AndroidProj.zip“ project
2. In the Assets > AndroidPacks see that folders are named “Pack1.androidpack“ and “NewPack1.androidpack“
3. See that “Build App Bundle (Google Play)“ is checked in the Android Build Settings
4. Build for Android

Expected result: ABB is built successfully
Actual result: Build fails with “Execution failed for task ':launcher:assetPackDebugPreBundleTask'.“

Reproducible with: 2020.3.41f1, 2021.3.12f1, 2022.1.20f1, 2022.2.0b12, 2023.1.0a15

Tested with: Windows 10

Note: not reproducible if folders are named differently (e.g. “Pack1.androidpack“ and “Pack2.androidpack“)
