Exception in thread "main" java.lang.NullPointerException     
    at net.minecraft.client.gui.ao.a(ao.java)     
    at net.minecraft.client.main.Main.main(Main.java)
这个是启动失败之后的显示的内容


一共两个问题 求大佬解决
俩问题缠了我快一周了

JAVA已换过  还是不行
文件也检查过了



JAVA空指针是我正在玩服务器的是 客户端突然未响应然后崩溃
之后就开始了，一直进不去

[1.15.2-1.7.10]能力整合-Forge/FabricAPI下的基础整合[持续更新]

不懂 我小白log是什么？

.minecraft/logs/latest.log

如果开启了版本隔离，就在.minecraft/version/游戏版本/logs/latest.log

换个启动器？

换个启动器试试

尝试重新下载你服务器的客户端

上传一下完整的错误日志

log就是日志文件

重新下载客户端

日志文件在一楼已经上传了

日志文件在一楼已经上传了 他显示的是客户端线程问题

试过了 一模一样的客户端 别人哪能用 我这里不行
JAVA重新下载也不行
内存也拉到合适的了
