"Adventure Time" achievement stuck at 0% on version 26.3

Version: 26.3

Issue: "Adventure Time" achievement stuck at 0%

Steps to reproduce:

1. Created two new survival worlds on Minecraft for Windows (version 26.3)

2. Cheats were never enabled (screenshot of world settings attached)

3. Spawned in Savanna biome in both worlds (should count as 1/17)

4. Explored multiple Overworld biomes including Forest, River, and Mushroom Fields

5. Checked achievement progress after each visit - still 0%

Expected result: Progress should increase when entering new biomes

Actual result: Progress remains at 0% for all Overworld biomes

Additional information:

1.Nether biome progress is working normally (confirmed by checking achievement details)

2.Other achievements (e.g., "Getting Wood", "Tourist") unlock without issues

3.Personally visited Mushroom Fields (rare biome) - progress still 0% (screenshot with coordinates attached)

4.This happens on both new worlds, not just one save file

5.Game is official Microsoft Store version, installed on a new PC with clean system

What I've tried (still not working):

1.Added the game folder to antivirus whitelist (Lenovo Anti-Virus)

2.Reset the app through Windows Settings

3.Restarted PC multiple times

4.Tested with different network environments (mobile hotspot)

Attached screenshots:

1. Achievement overview showing "Adventure Time" at 0%

2. Achievement details requiring 17 biomes

3. World settings showing cheats are OFF

4. Character standing in Mushroom Fields with coordinates visible

This appears to be a version-specific bug in 26.3. Please investigate.
