What happened?

Off topic: The version of the game that went wrong was 1.21.0, but I couldn't choose it, I could only choose 1.20.4+
题外话：出错的游戏版本为1.21.0，但是无法选择，我只能选择1.20.4+
I'm sorry because my English is not good, but the following is the content translated by the translation software

First of all, in someone else's server, when learning the vampire's move speed or attack speed skills, the character disconnects from the server, and then after a brief test, learning the skills in another branch will also appear (reducing blood consumption); Then I turned on the stand-alone creative mode, only kept the module for testing, and found that in the infection state, there will be an error when hanging up or clicking ESC, and the reason for the error is that the launcher shows an entity error, and the following log is a stand-alone error log, because I don't know how to get the server's (I disconnected the server directly, the server was not closed, only showed Negative index in crash report handler (0/14)
[00:47:58] [Server thread/WARN] [minecraft/PlayerDataStorage]: Failed to save player data for ccdotgtge）

The following is the original text in Chinese
首先是在别人服务器中，学习吸血鬼增加移速或者攻速技能时出现角色断开服务器的情况，之后简单测试了一下学习另一个分支中的技能也会出现（减少血液消耗）；然后我打开了单机创造模式，只保留了该模组进行测试，发现在感染状态下，挂机或者点击ESC会出现报错，报错原因启动器显示为实体错误，以下日志为单机的报错日志，因为服务器的我不知道怎么获取（我是直接断开服务器，服务器没有关闭，只显示 Negative index in crash report handler (0/14)
[00:47:58] [Server thread/WARN] [minecraft/PlayerDataStorage]: Failed to save player data for ccdotgtge）

Reproduce steps

一. The server encountered an error process

1. Being bitten by a vampire in the server;
2. Disconnect and roll back while waiting for the transformation, not sure how it happened, it happened 3 times, (error 1 occurred) Negative index in crash report handler (0/9) was displayed in the server, but after many attempts, it inexplicably succeeded in turning into a vampire
3. The second error occurs when learning the Enhanced Speed skill and the Reduce Blood Consumption skill, the learned skill is disconnected and the server displays Negative index in crash report handler (0/14) (Error 2)

二. Only open the module for testing under a single machine

1. Create a new world and create
2. Retrieve the Vampire Tooth from the inventory and right-click it
3. At this time, an error will be reported when you hang up or press ESC, and the error log has been uploaded on it

一、服务器遭遇错误过程
1.服务器中被吸血鬼咬一口；
2.等待变身时断开并回档，不确定如何发生的，发生了3次，（发生错误1）服务器内显示Negative index in crash report handler (0/9)）但多次尝试之后莫名就成功变为吸血鬼了
3.第二个错误发生在学习强化速度技能与减少消耗血液技能时，学习技能即断开同时服务器显示Negative index in crash report handler (0/14)（发生错误2）
二、单机下只开该模组进行测试
1.创建新世界开创造
2.物品栏调取吸血鬼牙齿，并右击
3.此时挂机或者按ESC即报错，报错日志已上传在上面
