I added the argument, here are the results: https://gist.github.com/luismss7/94522e87d59f469e7cd6abbf70050abb (client). Exactly, but the problem is that inside the world folder there is a corrupted file, and the FTB Backups mod stopped working so I don't have any backup different than the current save.

What do you mean by system property? The Java argument you told me to add to the server? I have done that, it removes the error, but I don't want to lose the actual world save as it is a shared server. I also know that it was cause by a conflict between two or more mods, as I have tried every mod separately and it didn't gave me a single error.

I added the argument and nothing showed up. I deleted all the files on my server except the world folder and it still gives me the same error. No mods are installed neither on the client or on the server. Here are the logs: https://gist.github.com/luismss7/76a47bb12c4706b471346a2b7ff19743

Hey! I keep getting this error whenever I try to join my moded Minecraft server. Here are both client and server full logs, and the custom modpack I use: https://gist.github.com/luismss7/6a7092f4181ee91ebe6ec6c6efdedd75 // https://drive.google.com/file/d/1DdZlmuEXUjgbOYQGyZxONlqv7AkFzeRI/view?usp=share_link
