Problem after renaming wordpress template file

Question

After renaming the files of my templates and inside the file with php, it is looking for the old templates. The dropdown is no longer available. Why is this happening and how to fix that?

The only files i modified is the template-parts folder inside the child theme. I did not touch the class-wp-theme.php where it is the warning.

If you have WP-CLI installed, try to run wp cache flush

or

you can put this code into your functions.php

function fix_template_caching( WP_Screen $current_screen ) {
    if ( ! in_array( $current_screen->base, array( 'post', 'edit', 'theme-editor' ), true ) ) {
        return;
    }
    $theme = wp_get_theme();
    if ( ! $theme ) {
        return;
    }
    $cache_hash    = md5( $theme->get_theme_root() . '/' . $theme->get_stylesheet() );
    $label         = sanitize_key( 'files_' . $cache_hash . '-' . $theme->get( 'Version' ) );
    $transient_key = substr( $label, 0, 29 ) . md5( $label );
    delete_transient( $transient_key );
}

add_action( 'current_screen', 'fix_template_caching' );
