Global resource packs fail to load or apply in the latest Preview

Steps to Reproduce:

1. Ensure you are running the latest version of Minecraft Preview.

2. Place a valid resource pack file (.mcpack or extracted folder) into the correct directory:

   • Windows: %appdata%\Roaming\Minecraft Bedrock Preview\Users\Shared\games\com.mojang\resource_packs\

   • Android: /storage/emulated/0/games/com.mojang/resource_packs/

3. Launch the game and navigate to Settings > Global Resources. The added pack should appear under "My Packs".

4. Select the resource pack and activate it by moving it to the "Active" column.

5. Create a new world (or load an existing one) with the resource pack supposedly enabled.

6. Observe the in-game textures, sounds, or other assets.

Expected Result:
The activated global resource pack should load correctly. The game's appearance and sounds should change according to the pack's content.

Actual Result:
The resource pack does not take effect. The game continues to use the default assets, even though the pack is listed as active in the Global Resources menu. This issue occurs consistently.
