The problem is probably from phase extension see

Phase • Animations made easy!

Seems like you’re enrolled for beta testing of the companion. The upcoming update of Kodular brings support for AndroidX, and that breaks the extension using Android support libraries. You can either roll back to the current stable version of the companion or use the updated AndroidX version of the extension from the MIT App Inventor community. PS: I’ll update this topic with new AndroidX version of extension as soon as Kodular releases the new update.

[Azad_Habibullayev]

yes use phase extenxion

Then see post above on how to solve it and also check here

This is a result of the error you’re getting. Which block are you using to change the background images?
