I need a minecraft magician to help me retrieve my world. I clearly fucked up real bad when my PC crashed mid project. It was about 12 hrs+ of work on a massive build
I'm going to guess there's no backup but it might still be possible to salvage. Based on the error, at least two chunks have malformed data that can't be decompressed. The first thing to try would be to attempt to open the world with MCA Selector. If it can identify and cope with the bad chunks, you can delete them and get back into the world.

MCA Selector help (Mac)
Hello all! This is a screenshot of the terminal for MCA selector when I try to install it on my Mac using these instructions: https://github.com/Querz/mcaselector/wiki/Installation
-
My backup size is getting to big
edit : MCA Selector is the solution i found it here after googling a while https://github.com/Querz/mcaselector

It's possible reset chunks in aternos server?
Try using a program like MCASelector: https://github.com/Querz/mcaselector/releases
-
So my world chunks can just swap with each other!?!?
I use MCASelector on my long run survival, it works pretty good
-
Is it possible to recover a Minecraft single player world with only the region folder?
Correct, that's the only thing left from that world. If you can load the region folder in MCASelector you'll get a top-down view of what's there.

Help with server issues? [java] 1.19.4
If it is caused by your explorers going out 20,000 blocks you could try using a tool like MCASelector to trim the world back down to a manageable size.

ITS OFFICIAL, Minecraft is set to release June 7th
Use MCAselector to prune the chunks you want to delete then load the world in 1.20 when it’s released and those chunks will regenerate.
- Is there a way to trim chunks remotely? (too large of world file to dl/up locally)
-
Predictably Random - Minecraft 1.20 Pre-release 1 is Out!
In case you don't know, there's https://github.com/Querz/mcaselector which can do this fairly easily: You can even filter chunks by how long players have been in them.

How to fix corrupted chunks in my minecraft server?
Your best bet is to either entirely delete the chunk or use an application like this

Help!! My 200h world is falling apart!
If you have other backups of the world without corrupted chunks in those locations, I would recommend using this tool: https://github.com/Fenixin/Minecraft-Region-Fixer

Paper 1.19.3 server freezes, java.io.FileOutputStream.write error in console
I'm unable to exactly trace down when did these errors start showing up because I only recently figured to use DiscordSRV to log the console, however, we first saw these issues after a player traveled so far and so fast from spawn that the server ended up running out of memory while that player was alone online (we have 4GB of RAM and the player went to 40+ thousands with an elytra or a boat). Since that caused the world to jump in size, I downloaded a copy of it and ran this region scanning script: https://github.com/Fenixin/Minecraft-Region-Fixer to rule out chunk corruption or something similar, and the script didn't find anything wrong.

Server struggling
Since you mention having backups, you can try using MCEdit to replace the bad chunk or use MC Region Fixer.
- I just lost all my worlds because of program error. This was my most recent and loved hardcore. I wanted so much more time with it...
-
Server hangs and crashes on world save, can anyone help?
Try running this on your world and deleting any corrupt chunks https://github.com/Fenixin/Minecraft-Region-Fixer. Make a backup first obviously.
-
Can anyone tell me why my MC world is being weird? The chunks wont load, I can't pick up items, and the mobs are glitching. This happens every time I join the world. I dont have mods or texture packs. I also cant leave my world, as it will stay on the 'saving world' screen unless I restart my pc.
That said, there was a forum thread where they would fix corrupted worlds, though it is no longer actively monitored and I don't know of any general "corrupted save recovery" place; otherwise, there is a tool, Minecraft Region Fixer, which will fix corrupted chunks (updated through 1.18; not sure if it will work on 1.19 but I don't think it made any changes to the save format), but may not be able to fix every issue (e.g. issues with specific blocks or entities). Note that in either case there may be data loss when resetting corrupted chunks/deleting entities/etc (best case is that no player builds were affected).
