    Disable Gradle 'offline mode' and sync project

Answer 1

Try adding the below code in the top-level build.gradle file

pluginManagement {

    repositories {
        maven {
            url 'https://jitpack.io'
        }
    }
}

Reference: https://docs.gradle.org/current/userguide/plugins.html#sec:subprojects_plugins_dsl

I have also added the below in settings.gradle

dependencyResolutionManagement {

    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}

After adding do invalidate caches and restart the app
