I found the issue, the issue was that when I downloaded the world from a realm, realms put strings around the version numbers of the packs in world_resource_packs.json and world_behavior_packs.json.

try settings the op-permission-level property in server.properties to 4

This also still effects the 1.20.60.21 beta / preview version. Also, this still happens when using RTX , not just with shaders, but it only happens when the "render dragon features for creators" experimental toggle is enabled. 

can confirm in 1.20.2

i have seen this issue also happening to multiple youtubers, such as eckosoldier, and they said that it happens when the experimental villager trade changes are enabled. 

this also affects 1.20.40.24 beta / preview

it still affects 1.20.15

The issue seems to get worse every time you open Minecraft, but uninstalling and re-installing fixes the issue, and you can keep your data by making a backup of the com.mojang folder, then when you re-install it replace the com.mojang folder with your backup of it. 

I FOUND A FIX FOR THIS, all you have to do is get bedrocklauncher, use that to install a previous version (make sure you check the checkbox to create a backup of your data), then once the previous version load up, switch back to the backup from the list of installed versions, then when Minecraft opens back up again then it is fixed, though once you do this you will not be able to update Minecraft through the Microsoft store unless you uninstall it and then re-install it, instead you will have to update it with the bedrocklauncher app, but when you use this method it uninstalls the current version and installs an older version, then uninstalls that older version and re-installs the current version and places back your data and fixed the issue, so you don't have to lose your data to fix the issues. 

This also happens on windows 11 as well, i have tried it on my gaming PC with an AMD rx-1660 gpu, and an core i7 cpu processor and 16 gb of ram (the PC is less than a year old btw) and on that PC the deferred technical preview runs fine most of the time but then it just randomly crashes, even on the lowest settings, so I do not think the issue is caused by the hardware, I’m pretty sure that this will happen on almost any device that tries to run the deferred technical preview. 

This bug has been fixed in the newest beta / preview: 1.20.20.20. 

@John Luciano Montgomery-Russo I LITTERALLY JUST SAID THAT EXACT THING AN ENTIRE WEEK AGO

The /execute rotated sub-command is also broken. There is a workaround for this, you just put "run execute" before you put positioned, rotated, or facing, i have more information on the workaround on my ticket for this here is the link [[MCPE-169945] /execute facing and /execute rotated and /execute positioned does not work in the /execute sub-commands on realms - Jira (mojang.com)|https://bugs.mojang.com/browse/MCPE-169945?filter=-2]

how is mine the duplicate because mine was posted first, also mine is more detailed than that other one

Also most of this stuff IS SUPPOSED TO BE IN VANILLA MINECRAFT, most of these features are accessible by enableing the education edition world toggle, also you can get the agent in Vanilla Minecraft by putting this command into an NPC and then activating it “/execute as @p run /agent turn left”

Where exactly in the game Files are these files located because I can’t seem to find them

This happens on windows 10 and windows 11 as well, I think the way to fix this would be to add a behavior pack with the .json item Files for the chalkboard, photo item, and portfolio from the education edition Vanilla behavior pack, the only problem is that I don’t know where in the education edition files the item definitions are or what file they are encoded in to. 

the facing entity sub-command is also broken for /execute in 1.19.80

this is an intentional feature that was added in 1.19.80

this also applies to 1.19.80
