eh和wnacg点击获取已下载的超过30多张图片时报错packaging failed, TypeError: Failed to fetch
按钮显示打包中，下载失败（重试）
但通过不断点击下载按钮有一定概率能下载，edge和chrome都出现这个问题
这是控制台内容：

这有个相同的问题反馈: https://gf.qytechs.cn/scripts/397848-comic-looms/discussions/295868

看起来像是你的浏览器限制了blob对象的大小，致使无法打包稍微大一些的图片集合。

不过那个人最后只是更新了下他的windows系统，问题就消失了。

我无法复现你的问题，由于浏览器与系统的多样性，要排查是相当困难的。你试试用其他浏览器如Firefox，看看问题是否依旧？
