Crash related to JSON

Hello, I opened my 1.16.5 2021.2 workspace in a 1.17.1 2021.3 client and Minecraft opens fine but when I click on create a new world the game instantly crashes.

Here is the crash report from the console :

https://pastebin.com/bAC7WxD8

The first thing it says is "Feature: Not a JSON object:", maybe 2021.3 didn't understand 2021.2 ?

 

When I open it with the Minecraft Launcher, it says :

com.google.gson.JsonParseException: Error loading registry data: Max must be at least min, min_inclusive: 13, max_inclusive: 4

Looks like this is caused by some biomes, but I don't really understand why this happens, would be happy to hear what's the problem, thank you.
