Android Studio tells me it cannot resolve classes in layout xml file but it compiles fine

Android Studio tells me it cannot resolve androidx.recyclerview.widget.RecyclerView and androidx.appcompat.widget.Toolbar in an xml layout file (main activity), but it compiles. The suggested fix (adding the dependancies do not work, since they already are). It isn't that big of a problem since it compiles fine but it still bothers me.

here's my layout file:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">

<androidx.appcompat.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    android:minHeight="?attr/actionBarSize"
    android:layout_alignParentTop="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    app:theme="@style/AppTheme.PopupOverlay">

    <ProgressBar
        android:id="@android:id/progress"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:indeterminate="true"
        android:visibility="gone" />
</androidx.appcompat.widget.Toolbar>



<androidx.recyclerview.widget.RecyclerView
    android:id="@android:id/list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/toolbar" />

And here's my build.gradle file with the dependancies:

buildscript {
repositories {
    jcenter()
    google()
}
dependencies {
    classpath 'com.android.tools.build:gradle:7.2.2'
}
}
apply plugin: 'com.android.application'

repositories {
    jcenter()
    google()
}

android {
    compileSdkVersion 32

    compileOptions {
        sourceCompatibility 1.8
        targetCompatibility 1.8
    }

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 32
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            //resources.srcDirs = ['src']
            java.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }
    }

    buildTypes {
        release {
            minifyEnabled false
        }
    }
}

dependencies {
    implementation 'androidx.recyclerview:recyclerview:1.2.1'
    implementation 'androidx.appcompat:appcompat:1.5.1'
    implementation 'com.google.android.material:material:1.6.1'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
}

Can anyone tell me what I did wrong here? Or is it a bug?
