Oculus是一个 Iris 的非官方 Forge 移植版，曾与铷模组有过很好的联动w

最近我看很多人有这个问题不知道怎么情况，那也就顺手一发吧！

（这个问题我都看多看吐了((）

直接看日志！

[19:53:40] [Datafixer Bootstrap/INFO]: 188 Datafixer optimizations took 1029 milliseconds

差不多都是这一茬   Error loading class: me/jellysquid/mods/sodium/啥啥啥的

（啥啥啥ClassNotFoundException -找不到类-）

而原因就是......

（铷(Rubidium)模组前身由钠(Sodium) 的基础上衍出来的，所以用的还是钠(Sodium)的名字，各位不要被误导了，以为自己安装了钠模组）

解决方案：

• 降级铷模组版本至1.20.6.5

• 不使用Oculus或铷

（如果帮到你了可以点个赞帮忙让更多人能知道自己出现的是这个崩溃吗~？）
