AndroidX ActionBar has disappeared: "Didn't find class "androidx.appcompat.app.ActionBar;" on path: DexPathList..." - android-actionbar

Question

Working on a fitness tracking app for portfolio using AndroidX dependencies, ran into the following error:
"E/LoadedApk: Unable to instantiate appComponentFactory
java.lang.ClassNotFoundException: Didn't find class "androidx.appcompat.app.ActionBar;" on path: DexPathList..." (Full error pasted below).
My actionbar won't appear, so neither will my menu options. In researching this problem, I see it might be a dependencies issue, so my dependencies in module:app are...
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'com.google.android.material:material:1.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
// Room components
implementation 'androidx.room:room-runtime:2.0.0'
annotationProcessor 'androidx.room:room-compiler:2.0.0'
androidTestImplementation 'androidx.room:room-testing:2.0.0'
// Lifecycle components
implementation 'androidx.lifecycle:lifecycle-extensions:2.0.0'
annotationProcessor 'androidx.lifecycle:lifecycle-compiler:2.0.0'
implementation 'androidx.recyclerview:recyclerview:1.0.0'
}
And in project...
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.4.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
ext {
roomVersion = '2.1.0-alpha06'
archLifecycleVersion = '2.1.0-alpha04'
}
Thank you in advance! If any other code would be helpful, I'll be happy to provide.
