+        提交前请确认：
+
+        * 该问题确实是 **HMCL 的错误**，而**不是 Minecraft 非正常退出**，如果你的 Minecraft 非正常退出，请前往 [QQ 群](https://docs.hmcl.net/groups.html)/[Discord 服务器](https://discord.gg/jVvC7HfM6U) 获取帮助。
+        * 你的启动器版本是**最新的预览版本**，可以点击 [此处](https://zkitefly.github.io/HMCL-Snapshot-Update/) 下载最新预览版本。

+
+        Before submitting, please confirm:
+
