app/build.gradle.kts:10

• The module no longer applies the Kotlin Android plugin. With Kotlin sources under app/src/main/... and a top-level kotlin { compilerOptions { ... } } block below, this is very likely to break configuration/compilation because the kotlin extension and Android/Kotlin compile tasks are provided by org.jetbrains.kotlin.android. Re-add alias(libs.plugins.kotlin.android) (or otherwise apply the Kotlin Android plugin) in this module.

plugins {
    alias(libs.plugins.android.application)
    alias(libs.plugins.detekt)
    alias(libs.plugins.junit5)
    alias(libs.plugins.kotlin.compose)
    alias(libs.plugins.kotlin.serialization)
    alias(libs.plugins.ksp)
    alias(libs.plugins.room)
