Render Problems with TabLayout and ViewHolder

I am currently unable to render am activity with just a TabLayout and ViewPager. I am getting this error:

Style ResourceReference{namespace=apk/res-auto, type=attr, name=textAppearanceButton} is not of type STYLE (instead attr)

From the following code:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".CompoundInterest">

    <com.google.android.material.tabs.TabLayout
        android:id="@+id/tabLayout"
        android:layout_width="409dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="86dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">

        <com.google.android.material.tabs.TabItem
            android:id="@+id/tabAbout"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="About" />

        <com.google.android.material.tabs.TabItem
            android:id="@+id/tabCalculator"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Calculator" />

    </com.google.android.material.tabs.TabLayout>

    <androidx.viewpager.widget.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@id/tabLayout" />
</androidx.constraintlayout.widget.ConstraintLayout>

I added the TabLayout and ViewPager to an otherwise blank, new layout and they have never rendered, even after being 'connected' to the fragments.

Go to the Android View, find the Gradle Scripts - build.gralde(Module :App) then edit it. change

implementation 'com.google.android.material:material:1.9.0'

to

implementation 'com.google.android.material:material:1.7.0'

Finally, click Sync Project with Gradle Files, wait a minute, it would be fine.

There seems to be a problem with version 1.8.0.

Other Material Design examples TabItems in TabLaout are also having rendering issues.

Downgrading to 1.7.0 works fine.
