That looks like the MIT packaged Android emulator and Companion.
It's probably not AI2 Offline, we don't support that anyway.
To use Ai2 you have to start a web session at httlp://ai2.appinventor.mit.edu
then start a Project.
Either Build an apk file or run the Project from the Connect->Companion menu.
Personally, I don't use the aistarter MIT emulator. It's like putting on your socks and shoes in one step..
I run the MIT Companion app on BlueStacks 5, or on my Android phone.
