补充信息

原始信息已被混淆，这是使用mapping.txt 解混淆的结果，可能有出入。

我无法在不混淆的情况下复现错误，因为我的安卓死丢丢有BUG，只要proguard为false，就告诉我找不到$j类，很神奇

这还是大概率是你的混淆或者优化问题，改变了代码逻辑

倒也不一定，因为我发现只有这一个用户有这个问题，其他人都是稳定运行的，而且我查阅到崩溃有关发生在

    operator fun get(id: Long): GroupMemberListCache {
        return map.getOrPut(id) {
            val file = resolveCacheFile(id)
            if (file.exists() && file.isFile) {
                val text = file.readText()
                if (text.isNotBlank()) {
                    return JsonForCache.decodeFromString(GroupMemberListCache.serializer(), text)
                }
            }

            GroupMemberListCache(0, emptyList())
        }
    }

readText发生的错误，而通过查阅资料MalformedInputException: Input length = 1得知，这很可能是文件编码问题（极有可能所写入文件一半被安卓系统意外杀死导致文件损坏），但我并不确定，也许可以加个容错机制。
特别的，我要求用户自行删除了缓存文件，问题消失了
