I have been following a tutorial from Udemy called The Complete Android 12 & Kotlin Development Masterclass. I was working on the quiz app part and tried to start a new activity, at which point the app fails.
Even though I tried to copy the code exactly from the reference, I am still getting a fatal error at the main, caused by android.view.InflateException, android.content.res.Resources$NotFoundException, and java.lang.ClassNotFoundException. Below is the complete error message.
The reference Github link: https://github.com/tutorialseu/QuizApp/tree/setting_up_the_question_ui

You have written "Shape" instead of "shape".
