This is an issue about modifing all the texture2d assets' name in an AB contains texture2D and Sprite assets

[544051996]

`AssetsManager manager = new AssetsManager();
var bunInst = manager.LoadBundleFile(bundlePath);
var bun = bunInst.file;
int fileTotal = bun.GetAllFileNames().Count;

for(int i = 0; i<fileTotal; i++)
{
var afileInst = manager.LoadAssetsFileFromBundle(bunInst, i, true);
var afile = afileInst.file;
foreach(var texInfo in afile.GetAssetsOfType(AssetClassID.Texture2D))
{
var texBase = manager.GetBaseField(afileInst, texInfo);
.......
}
}`

For AB contains both texture2D and Sprite assets, there is a NullReferenceException:Object reference not set to an instance of an object. AssetsTools.NET.Extra.AssetsManager.GetTemplateBaseField.
AssetsTools.NET.Extra.AssetsReadFlags.readFlags.
AssetsTools.NET.Extra.AssetsManager.GetTemplateBaseField.

For AB only contains texture2D asset it goes well and modified all the texture2D name successfully

GetTemplateBaseField is a big method so it could be anywhere. I doubt it has to do with sprites being in the bundle. Maybe check if your bundle has a type tree with afile.Metadata.TypeTreeEnabled? If it's not enabled, you need to load a tpk.
