从信息上看来，是用了DICTIONNARY的问题。经过查阅资料，发现问题出在迭代修改DICTIONARY的地方：
foreach (string key in dict.Keys)
{
}
不可以迭代去修改dictionnary,正如我看到一个帖子写的：
You are modifying the dictionary while iterating over it. This is a big no-no.
批量修改或删除应当先将其作为BUFFER引出来再改，然后在一个个删除。
var buffer = new List<KeyKode>(Controlekeys.Keys);
foreach(var key in buffer)
{
//修改你想要修改的东西
}
===================我直接获取引用来删除:如下记录=========================
AssetBundleRef[] abRefs = new AssetBundleRef[dictAssetBundleRefs.Count];
int i = 0;
foreach (string key in dictAssetBundleRefs.Keys)
{
}
i--;
for (int j = 0; j < abRefs.Length; j++)
{
}
