[MCPE-228593] PlayStation: World fails to load after 1.21.111 update (Error Code: Panda

Summary

World fails to load after enabling experimental features (Error Code: Panda – Prospero Error Detail Prerequisites-12)

Steps to Reproduce

Create or load a world on PS4.
Transfer/save it to PS5.
Enable multiple Experimental Features (including one that was later removed in v1.21.111).
Build extensively in the world (large city + mansion).
Update to Minecraft Bedrock v1.21.111.
Attempt to load the world.

Observed Results

World fails to load entirely.

Error code appears:

Panda (Prospero Error Detail Prerequisites-12).

Unable to access or convert/save the world further.

Expected Results

World should load normally after update.

If experimental features are deprecated, the game should provide a safe fallback or conversion option instead of preventing world access entirely.

Notes

The world is approximately 1.5 GB in size.

Issue may be linked to missing/removed experimental features that were enabled prior to the update.

I also have 3 mods attached to the world. Unsure if these affect the failure, but issue persists even after disabling content packs.

Last successful save was 11:58 PM, just before updating to v1.21.111.

My theory is that after using the experimental golums the update may possibly caused an effect to where the world doesn't want to load. I've had this world since 2016 PS4 version and extensively built a whole city with a lot of major builds 1040 hours of play time just on PS5 not including PS4. I reached out to Mojang support and this is my last call before I have to wait and hope for the next patch/update that it would fix this. Any way to further investigate this?

Environment

Platform: PlayStation 5 (Digital)

World Origin: Originally created on PlayStation 4, later imported/bridged to PS5

World Size: ~1.5 GB (large build: city + mansion)

Storage: Local PS5 save + cloud save (both fail)

Mods/Add-ons: 3 attached; also tested with all disabled → still fails

Experimental Features: New Golem toggle was enabled before update

Network: Fails both offline and online

Last Known Working Version: 1.21.0 (before 1.21.111 update)

Could you share the world file here to help the qa team to test further?.

Ian walsh 2025-10-02T14:48:18Z

How do I do that it's on PS5

Cinese 2025-10-06T15:04:03Z

Maybe with a USB stick, but I doubt it.

Ian walsh 2025-10-06T15:24:39Z

Fixed it. After multiple attempts re downloading from cloud backup and changing settings reporting it's finally back!! Ty

Ian walsh 2025-10-06T15:29:17Z

Recommend changing to the original Minecraft skin and default settings after downloading backup

Which settings may I ask?

DonCiro 2025-10-06T15:55:09Z

What settings man

Ian walsh 2025-10-06T17:05:30Z

All of them it took multiple attempts I turned on every setting and turned off what I could . I finally got it to start reporting straight from PS5 and after I changed skins on default (was already on before) I think that's the setting that got it to load. I did all this after I re downloading my back up file from cloud. I tried all of this a few days ago out of being desperate I kept trying to load it over and over again reporting each time. Then it magically loaded. I'm not completely sure what I did but just mess around. Delete cache as well that could of helped.

Ian walsh 2025-10-06T17:07:05Z

Just don't upload to realms if your file is over 600 MB just to be safe may corrupt or change and delete your world. If you do anything just make sure you have a back up. I couldn't duplicate my world file is 1.5gb

DonCiro 2025-10-06T17:25:18Z

So you just activated settings at random? It seems strange to me but I will try

Cinese 2025-10-06T19:17:21Z

It doesn't work all the time. I guess is all about luck. I'll wait for an official update from Mojang.

Ian walsh 2025-10-07T16:27:43Z

Well just of today it started giving me the panda error again 😭

I'm a PS5 user, but after installing the Bronze Update on 1st October, I encountered this bug. The world size was 1000MB, and I had put it into Rest Mode without saving immediately before the update, then proceeded with the update

Same issue here — my long-term world (around 4.3 GB) was originally created on PS4 and played on PS5 for years without issue.
After updating to version 1.21.111, the world fails to load and crashes with the same “Error Code: Panda (Prospero Prerequisites-12)”.
Save data is still intact locally and in cloud storage, so the world file definitely exists — it just can’t be read.
I’m hoping a recovery or patch will fix this soon.
Thanks for continuing to look into it — this world means a lot to me.

Found out Minecraft memory is only 9 gb on PS5. Your save cache may be full. Back it up on cloud before anything

you 2025-10-20T17:41:29Z

Today, after updating Minecraft, the bug has been fixed! I'm delighted to be able to enter the world again. I'm a PS5 user. Version 01.032.000
