Various Legacy Texture/Mash-Up Packs fail to install from Marketplace and return to download/update button.

Various Legacy Texture/Mash-Up Packs, such as the Natural Texture Pack and LittleBigPlanet Mash-Up Pack, cannot currently be installed or updated from the Minecraft Marketplace.

When attempting to download these packs, the download progress reaches 100%, briefly shows an "Installing" dialog, and then immediately returns to the Marketplace page for the pack. The download button reappears but no longer responds when clicked.

Steps to reproduce:

1. Open Minecraft Bedrock Edition.

2. Go to the Marketplace.

3. Navigate to one of the affected packs.

4. Attempt to download and install the pack.

Result:
The download reaches 100%, an install dialog briefly flashes, then the Marketplace page reloads and the download/update button appears again but becomes non-functional.

Expected result:
The pack should install normally and appear in owned resource packs and/or world templates.

Additional information:

• The issue occurs with multiple legacy packs (see the list of affected packs below).

• The issue occurs on multiple platforms (see the list of affected platforms below).

• Some legacy mash-up packs, such as the Norse Mythology and Halloween packs, download and install normally.

• Clearing cached data, restarting the game, and reinstalling the game does not resolve the issue.

• Most of these legacy packs also lack textures for “newly” introduced blocks/items, while some of these packs have not been updated for a very long while. This issue honestly deserves a whole separate, more detailed, bug report.

Affected packs:

• Natural Texture Pack

• LittleBigPlanet Mash-Up Pack

Affected platforms:

• Windows 11

• Android 16

• iOS 26

• Xbox One
