It's been a while since I got to work on an MC server, so obviously I decided to upgrade the entire server: I switched from spigot to papermc and I was using version 1.18.2 and I wanted to upgrade to 1.20.4 before backing up the world. When I first started the server, I ran into this error:
[Server thread/ERROR]: Failed to read chunk
Here's the log:
[18:25:05] [Worker-Main-2/INFO]: Preparing spawn area: 5%

And after some research I thought it was just a problem of write and read permissions to give to the file or to the entire folder, and so I did, but always in vain.

What am I doing wrong? I gave permissions to each folder/file even though it doesn't seem like the right thing to do, but why hasn't anything been unlocked yet?
Thanks for your help and have Happy Holidays!
