Cannot migrate to Android 13

Question

I'm trying to migrate my app to Android 13, but I can't manage to do so. I have the following contents in by main module gradle build file:

android {
    // Android Build Settings
    compileSdk 33
    buildToolsVersion "33.0.0"
    ndkVersion "25.0.8528842"

    defaultConfig {
        applicationId "..."
        minSdk 24
        targetSdk 33
        ...
    }

    ...

And I'm using version 7.2.1 of AGP:

buildscript {
    repositories {
        google()
        mavenCentral()
        ...
    }
    dependencies {
        // Build tools
        classpath 'com.android.tools.build:gradle:7.2.1'
        classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.21'

        ...
    }
}

Those are the steps required by Google, but when I sync the project something is completely wrong. For example, all the manifest entries are marked as Unknown attribute android:.... I've tried using the latest canary version "Android Studio Electric Eel | 2022.1.1 Canary 6", downloaded the latest versions of the Android's SDK "Android TiramisuPrivacySandbox Preview" (TiramisuPrivacySandbox), "Android Tiramisu (Tiramisu)" (33) and "Android Tiramisu Preview" (Tiramisu). I've also checked that I have downloaded "Android SDK Build Tools 33", cleaned and rebuilt the project, cleaned and restarted Android Studio.

What am I doing wrong? Thanks in advance.
