运行环境

目前反馈的用户都是ios的， unity 2019.4.29f1c109  wx-sdk 20240118

[zyrshui]

目前反馈的都是 ios 8.0.53的

[zyrshui]

定位到Physics.Raycast(ray, out hit, Mathf.Infinity, 1 << LayerMask.NameToLayer("Ground")) 引起的崩溃，Physics.Raycast在小游戏里为啥会崩溃呢，

[zyrshui]

每天几百个报错都是ios的，安卓和pc都没有问题，怀疑是ios微信的和unity的兼容问题，怎么解决呢

[Oooocean]

是否联系到玩家，或者是否有复现路径？

[zyrshui]

大部分是切换场景的时候，发生的

[zyrshui]

这个报错每次都伴随这 WXAssetBundle 加载一个二进制数据 downloadHandler.data 为空的情况，已经判定了 string.IsNullOrEmpty(www.error) 但有时downloadHandler.data 为空，很奇怪

这个报错每次都伴随这 WXAssetBundle 加载一个二进制数据 downloadHandler.data 为空的情况，已经判定了 string.IsNullOrEmpty(www.error) 但有时downloadHandler.data 为空，很奇怪

正常情况下 downloadHandler.data 就是空的，应该跟这个没关系。你说的是不是 bundle 是空的？麻烦联系小助手提供下完整日志。
