Some changes have been made in managing the Azure SDK libs, but the plugin behaves differently when installed from the Marketplace and when installed directly into the project folder.
The plugin currently makes a copy of the Azure binaries to the plugin’s Binaries folder using the Engine’s linking system to organize the dependencies in the packaged project, but this copy is not happening when the plugin is installed from the marketplace, so the libraries end up not being loaded in the editor.
I’m making the necessary corrections, but at the moment will be needed to download the plugin via GitHub releases to use without crashes.
