Network protocol error with vanilla client and upgrading world.

So... ummmm, forge "1.2.11"? Do you mean forge "1.21.11" (as said in your crash report)? If you really meant what you said, then you're really gonna' have to provide a download link here (and maybe even a time machine). Also, please specify the exact version of forge that you are using. Because your crash report is completely obfuscated (for whatever reason), people are going to need access to the mappings in order to make sense of this crash report. Provide all of this (the mappings should be easily accessible if you provide the exact forge version), and I will edit this crash report to make much more sense and post it back here via pastebin. Hopefully then it will be much easier for others to answer your question.

I will say though, just based on the error message I can see, chances are likely slim that you can use a vanilla client. These reasons would take a little while to get into, but even if chances look slim, you shouldn't let this discourage you; you never really know if a problem like this can't be solved unless we try.

Hope this can help us get somewhere easier to work with.
Let me know!

Minecraft crashed after I ran out of storage on one of my disk drives

Alright, I have taken a look at the crash report you have provided and cross referenced it to the source code. It turns out that my theory is true! Strangely, when writing information to a save file, enigmatic legacy will just update the file and push all of its edits upon an error occurring. If it weren't for that, this issue probably wouldn't be happening. The problematic file you are looking for should be located directly in your world save folder in a file named "soul_archive.json". If you are having trouble finding this file, try using the search field in file explorer. The most direct solution to your issue at hand would be to delete this file directly. However, this file may be able to be repaired, but this option is up to you if you wish to pursue. Luckily for you, the file should be in a readable format. You can open it in notepad or some other text editor to view the contents. If you are having trouble detecting and solving issues within this file, you could try sending the raw contents of it through pastebin to this thread. I can take a look and send the modified contents back to you through pastebin, or if I could find no solution, I will let you know, in which case you should simply default to deleting the file.

Please let me know if you encounter any unexpected issues or if something I said is unclear to you; I will help to the best of my ability.

Network protocol error with vanilla client and upgrading world.

Not sure if this can be regarded as an issue or not but I'll describe the symptoms and will be interested in the comments.
I have a 1.2.10 world and have been playing on a server modded with FallingTree using vanilla clients. As 1.2.11 is out, I wanted to upgrade the world so I installed forge 1.2.11 on the server and copied the world over (I maintain a new directory for each version). Upon trying to access the server with a vanilla client, I get a Network Protocol Error and get kicked off.
However, if I try to access the server with a vanilla client and allow the server to create a new world, no error. If I use a forge client with the old, no error. It seems to be the specific combination of using an existing world and the vanilla client.
For my purposes right now, I'm fine with using Forge clients. It would be nice to be able to use vanilla (since the mod I use doesn't require client modding). Just wondering if this is in any way possible.
Note that I tried removing FallingTree just in case and it made no difference.
The logs show
