It is pretty standard for a world to get corrupted in Minecraft. It gives various kinds of error messages such as “There was a problem loading this world” or “Disconnected due to world corruption“. In this post, we will talk about this issue and see what you can do to fix a Minecraft Corrupted World.
There was a problem loading this world
What does it mean when Minecraft says Disconnected due to world corruption
If Minecraft says that a world is corrupted, this means that the files of the world that you have created have been corrupted. There are various reasons for the same, from hard disk crashes to forces shutdown, and everything in between can corrupt your world in Minecraft.
However, this doesn’t mean that every single file of your world is corrupt, there are some files that contain all the information about your world which can be used to restore your old world. Check the solutions mentioned later, we have shown how to use those files to restore the corrupted world.
Fix Minecraft Corrupted World
To fix Minecraft Corrupted World, you can try any of the following solutions.
- Generate the corrupted world using the JSON file
- Create a new world and copy the old game files
- Use Backup and Restore
- Reset Minecraft
- Troubleshoot in Clean Boot
Let us talk about them in detail.
1] Generate the corrupted world using the JSON file
A JSON file contains information about the world that got corrupted. We need to fetch the information from the JSON file and see if that helps. Follow the prescribed steps to do the same.
- Open Minecraft.
- Go to the world that got corrupted and then click on Edit.
- Now, click on the Export World Generation Settings button to create the JSON file that we are going to use later.
- Then, click on the Create New World button and then on More World Options.
- You need to click on Import Settings, which will launch File Explorer.
- In the address bar, type %appdata% and hit Enter.
- Go to .minecraft > saves.
- Open the world that is corrupted.
- Launch worldgen_settings_export.json.
Once the world is generated, check if the issue exists.
2] Create a new world and copy the old game files
If exporting the information from the JSON file didn’t work for you, try creating a new world and coping the old game files to it. This solution should do the job for you regardless of the Minecraft version you are using. Follow the prescribed steps to do the same.
- Open Minecraft and create a new world.
- Once a new world is created, open Run, type %appdata% and click Ok.
- Next, go to .minecraft > saves.
- Then, open the world that got corrupted.
- Look for level.dat, level.dat_mcr, level.dat_old, and session.lock. Some of the files might be missing from the corrupted world folder, there is nothing to worry about.
- Copy those files and paste them into the new world folder.
Finally, launch the new world and hopefully, your issue will be resolved.
3] Use Backup and Restore
Some users were able to create a backup of the folder even after it got corrupted. We should try to do the same, create a backup of our old world and restore it to the new one. First of all, open Minecraft, select the corrupted world, and click Edit. Then, click on the Make Backups button. This will create a folder called backups inside of the folder of the corrupted world.
You then have to copy the folder and paste it inside the new world. Open Minecraft once again, edit the new world, and click on the Open Backup folder option. Follow the on-screen instructions to add the folder.
4] Reset Minecraft
If your worlds keep getting corrupted, even after creating a new fresh one, then maybe there is something wrong with the Minecraft app on your computer. We are going to reset Minecraft and see if that works.
There are various ways to do the same, but first of all, let us see how to do the same using Windows Settings.
- Open Settings.
- Go to Apps > Apps & features.
- Search for Minecraft.
- Windows 11: Click on the three vertical dots and select Advanced Options. Windows 10: Select the app and click on Advanced Options.
- Click on the Reset button.
Let the app reset. You can also go to %appdata from Run, then to the .minecraft folder, and delete resources, Bin, mods, and config folders. Now, update Minecraft from the Microsoft Store.
Both the methods can do the job for you.

There are a lot of other applications that can interfere with Minecraft and corrupt your world. We can not just name an app without any conclusive evidence. So, let us perform Clean Boot to boil down the possibility and find out the culprit. You have to keep all the Minecraft-related processes along with that of Microsoft. Then, you need to manually enable processes to find the troublemaker. Once you know the culprit, just delete it and your issue will be resolved. You can then create a new world, and restore your files from the previous games.
Hopefully, you are able to resolve the issue using the solutions mentioned here.
