Steps to reproduce:
Create a new world with a world template
Observed result:
You do not enter the world that is supposed to be generated by the template, instead you enter a regular/superflat/void world.
Expected result:
You enter the world that is generated by the template.
Tested world templates:
Halloween Mash-up Pack
Neon District RTX
Trial Chamber Legends
15 Year Journey
Farm Life (by PixelHeads)
Trident City (by Shaliquinn's Schematics)
Original description:
Some older worlds I have from the Marketplace no longer work when they are created or reopened. When I open these worlds that have already been created they change to appear like a normal world. My current known examples are the Farm Life world (made by PixelHeads) and the Trident City world (Shaliquinn's Schematics). Please fix this, as I have lost a world in which I have put in several hours building things. Below are the before and after images of the worlds. (also first report so i might have messed up)

I could not reproduce this after resetting Minecraft, so this seems like an issue with instances that upgraded to 1.21.20.
I had the same issue with the Tetris DLC template a couple days ago, on version 1.21.20 (I'm also on Windows). I tried to create a new world several times and ran into the issue, but after restarting the game it went away. I restarted several times while my friend was attempting to connect to the world (we had trouble, probably related to MCPE-185254) and the issue did appear again (ruining the new world that had previously worked), but went away again after restarting the game. I have been unable to reproduce the bug while playing today on 1.21.21, despite restarting my game multiple times. I figured I'd add what I have found, since the Tetris DLC template is a newer template which means that the age of the templates was probably not the issue.

The problem is similar provided additional materials in the task MCPE-185527
Based of the comment I made on the relating report, the bug may be a result of an issue with Marketplace decryption, and so this (and the relating bug) could be reproduced, so maybe every Marketplace content players had downloaded is affected. However (for me) I got it temporary solved by restarting the game multiple times (until my Windows 11 PC (the affected computer) was rebooted). Strangely, I cannot reproduce it on my Windows 10 PC (main computer).
My issue duplicates every time in 3 days and my issue is on XBOX. Issue reports by me on XBOX and this is for windows only.
This is affecting all the new purchase and still it seems no work has been done for past 10 days

Even though it got fixed in the 1.21.31 hotfix it has happened again with me with "The Ultimate Survival World" by RareLoot in December so i hope this gets fixed again (Edit: im on PS4)
