Level.dat, Level.dat_old and player files in the playerdata folder can become corrupt in certain situations
Please attach the console log of your game using these instructions after having done the following:
- Open a world
- Make some changes to it, ones that will likely lead to corruption
- Leave the world
- If the world has disappeared from your saves list, please copy the log and provide it here - if not, please start again with Step 1.
To make the world appear again in the saves list, you can rename the newest of the "level##########.dat" file to "level.dat" in the folder of the save affected by this.
When an update is given to a tile entity ( adding items into a chest, placing a chest... etc). directly before saving and exiting a world, the level.dat file is deleted or lost (don't know). this now only loses any inventory and disappearing from the in-game world list. the way i temp fix it is to use a backup of the world and simply copy the level.dat and level.dat_old onto the non-backup world

Hi there!
This sounds like a duplicate of MC-193198, and I'm copying the moderator note from that report to this comment so you know what to do next.
Although a lot of people have experienced this issue, we're still not sure of the cause; that's why we're asking for this information.
Please attach the console log of your game from the exact time the world has gone missing from the game using these instructions to MC-193198.
Also, there's a workaround that you can use to recover the world (but if you have the information requested above, please attach it!):
To make the world appear again in the saves list, you can rename the newest of the "level##########.dat" file to "level.dat" in the folder of the save affected by this.
Thank you for your report!

My friends World has disappeared and will not show up in his single-player worlds yet it is still in the saves folder in .minecraft. After looking to see if this was a problem I found issue MC-193198 which has the same problem where their world is gone but my friend's level.dat file has no change to it. He sent me the world file and everything seems normal but the world doesn't show up in my single-player worlds either.
WORLD FILE : https://www.mediafire.com/file/0hntymbvc9ase7j/file
Very very strange - this is an extension of MC-193198. Please follow the instructions in the moderator note on that report, as we really really need to see a log of this occurring.
By the way, if you have not figured it out, just renaming the corrupted files (the one containing all the extra numbers at the end) can restore the lost player data.

Please provide a screenshot of your game while you are in the world with your F3 debug screen enabled.
I
can't get into a world with the files deleted(or don't know how). this is a world where it has happened repeatedly
here is a video of the file deletion. I cut out the middle of failed attempts on the same world.file deletion part 1.mp4
file deletion part 2.mp4
Do you have any third party programs that are related to Minecraft save files installed on your device, and if so, does it still happen without them installed? Please also remove any bad antivirus programs like Norton or McAfee, and run a scan with Malwarebytes.
Could you also please update a couple of the "level#####################.dat" files?
And how do i fix it?
@Daan: We are still investigating the issue, if you open your save folder and have any of the "level################.dat" (lots of numbers) files, please upload a couple.
If you are experiencing this issue, please attach some of the files with the odd filename with the numbers for us to take a look at.

I can't play minecraft anymore, because every world i start in, gets deleted.
Based on the information given in
MC-197540, this also seems to occur on Open to LAN with playerdata .dat files, suggesting that this is likely connected to player-specific parts of the level.dat.latest.log
Just occurred to me in 1.16.4, I will attach the console log from the time of the error. It appears to not be related to tile entities, as during the short period of time I was in the world prior to the level.dat error no tile entities were interacted with.
To replicate, you simply need to open either level.dat or level.dat_old with NBTExplorer (unsure if similar programs effect it the same), and then open the world. This causes the level##################.dat to generate, meaning it occurs on world load, not on world save. Also this is on a Windows environment
Um, wait, so you keep that NBTExplorer open for whole time? If yes, then it's not valid way of replication, since external program (that user opened themselves) is preventing Minecraft from writing to that file.
Yes, and that was my thought as well. Somebody else has been able to replicate it without using an external program, but they are unsure how
I was able to create a level##########.dat, however it was not kept in the folder. I did capture the exact moment it occured though - https://www.youtube.com/watch?v=gFXMC6DG56o
Can confirm in 1.19.3 and 23w04a
