我安装的forge版本是2768，官网下载，安装完毕之后点开始游戏，下载完便跳出来如图所示的这个东西，且没有产生崩溃报告。
所以请问应该如何解决？

尝试重新安装。

或者直接用别人的整合包 https://www.mcbbs.net/forum.php?mod=viewthread&tid=869469

那请问如何重新安装？是把forge安装包打开重装还是网上重新下载forge？重装前需不需要删除些什么？在这方面我还是个小白

删除之前安装的，然后再打开安装。

另外，不建议用 2768，建议用 2847

楼主是否装了材质包

没有装，只有1.13.2装了个Optifine

https://wenwen.sogou.com/z/q828905740.htm可以看看这个对你是否有帮助

我网上没找到forge删除的具体办法，我可不可以不删除直接再重新下个2847的？

启动器中找到删除版本啊，不删除也可以的

重新下载一下试试

好的明白了

刚才下了2847，还是会崩溃，我在入正前还下了一个网易的mc，会不会是网易mc的问题？

试试我这个整合包 https://pan.baidu.com/s/1nm7Yvn91j4FX2BdIhpEUeQ

谢谢了，我猜测可能是跟1.13.2的OptiFine有关系，之前只知道它不和1.13.2的Forge兼容
