Underline, cursor and hint disappeared at TextInputEditText in TextInputLayout on focus

Question

I have an edit profile screen with bunch of TextInputEditTexts. It worked fine before, but now on focus underline, cursor and hint become invisible.

Has anyone faced the same problem?

...

    <com.google.android.material.textfield.TextInputLayout
        android:id="@+id/tilFirstName"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:layout_constraintStart_toEndOf="@id/ivContactIcon"
        app:layout_constraintEnd_toEndOf="@id/gEnd"
        app:layout_constraintTop_toBottomOf="@id/toolbar"
        android:layout_marginStart="@dimen/margin_32"
        android:layout_marginTop="@dimen/margin_24"
        android:hint="@string/profile_edit_hint_first_name"
        >

        <com.google.android.material.textfield.TextInputEditText
            android:id="@+id/etFirstName"
            android:layout_height="wrap_content"
            style="@style/FontRoboRegularSizeMFontPrimaryOneLineMatchWrap"
            tools:text="Oleh"
            android:inputType="textCapWords"
            android:maxLines="1"
            android:nextFocusForward="@id/etLastName"
            android:imeOptions="actionNext"
            />
    </com.google.android.material.textfield.TextInputLayout>

UPDATE: After changing background of the root element it's clear that these elements become white. not disappeared.

The default style used by the TextInputLayout is

<style name="Widget.MaterialComponents.TextInputLayout.FilledBox" parent="Base.Widget.MaterialComponents.TextInputLayout">
    <!-- underline color in FilledBox style -->
    <item name="boxStrokeColor">@color/mtrl_filled_stroke_color</item>

    <!-- The color of the label when it is collapsed and the text field is active -->
    <item name="hintTextColor">?attr/colorPrimary</item>
    ....
</style>

The mtrl_filled_stroke_color is based on the colorOnSurface.

Check in your theme the colorPrimary and the colorOnSurface values, or use a custom style with the same attributes described above.
