不管是服务器还是单人，一进游戏就崩溃，不管是原版还是整合包，换了其它客户端和存档都一样，求解

把 .minecraft 文件夹中 crash-reports 文件夹中的最新文件发给我。

我住宿的，现在回学校了，要下个星期才能给你，很抱歉

好的，下次务必记得要放崩溃报告。

没有就是盲猜

无论单人服务器联机
无论什么客户端全是崩溃？
那么就是以下几个地方出问题了：
1.内存分配
2.显卡驱动
3.Java
4.启动器
5.操作系统
除此以外基本上就没有其他可能性了

是这个嘛？

尝试关闭防火墙和删除国产杀毒软件呢

搜索了一下：https://blog.csdn.net/feilong2483/article/details/78682205
看样子需要重置网络配置
以管理员身份运行cmd，输入并回车
重启应该就好了

真的唉！可以了！

试过，没用，不过现在弄好了，多谢你的帮忙
