Resolution Note (fix version 2020.2):
User error.
There are two issues with the project.
First, incorrect use of Uri, the line 48 in LoadAssetObjects.cs has to be:
string fullURL = new Uri( Path.Combine(path, localasset)).AbsoluteUri;
note the AbsoluteUri, not AbsolutePath property at the end.
The second issue is with the AssetBundle build script (Exporter.cs). It builds bundles passing EditorUserBuildSettings.activeBuildTarget as build target. This means that if Android is selected, the bundles are built for Android and are technically incompatible with Editor though for simple primitives may actually work, by chance, not by design.
On latest trunk it doesn't reproduce for me in Editor, but I do believe that is the issue. In order load AssetBundle in Editor, the bundle has to be built for Standalone.
