[TabLayout] Instantiation error in AndroidStudio

See original GitHub issue

Description: When I use the library com.google.android.material:material:1.8.0-alhpa01 and add a TabLayout to any layout in AndroidStudio, I get the following notice:

java.lang.IllegalArgumentException: Motion easing theme attribute must be an @interpolator resource for ?attr/motionEasing*Interpolator attributes or a string for ?attr/motionEasing* attributes.

Expected behavior: AndroidStudio should show a preview of the TabLayout

Source code:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.google.android.material.tabs.TabLayout
        android:id="@+id/tabLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <androidx.viewpager2.widget.ViewPager2
        android:id="@+id/viewPager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/tabLayout" />

</RelativeLayout>

@Gizmodo @shalva97 @daniel-reinhold I just tested the latest Android Studio canary build (2022.2.1) with 1.8.0-alpha03 and the layout preview works for me again! The latest release candidate of Electric Eel still doesn’t work, so I think I will work with Flamingo for the next months.
