Fatal error with WordPress 5 Beta 3

Just FYI…After installing Metaslider v 3.10.0 on WordPress 5.0-beta3-43876, I encountered this error when trying to edit a page (any page):

Fatal error: Uncaught Error: Call to undefined function gutenberg_get_jed_locale_data() in C:\laragon\www\tic\wp-content\plugins\ml-slider\admin\Gutenberg.php:42 Stack trace: #0 C:\laragon\www\tic\wp-includes\class-wp-hook.php(286): MetaSlider_Gutenberg->enqueue_block_scripts(”) #1 C:\laragon\www\tic\wp-includes\class-wp-hook.php(310): WP_Hook->apply_filters(NULL, Array) #2 C:\laragon\www\tic\wp-includes\plugin.php(453): WP_Hook->do_action(Array) #3 C:\laragon\www\tic\wp-admin\edit-form-blocks.php(390): do_action(‘enqueue_block_e…’) #4 C:\laragon\www\tic\wp-admin\post.php(160): include(‘C:\\laragon\\www\\…’) #5 {main} thrown in C:\laragon\www\tic\wp-content\plugins\ml-slider\admin\Gutenberg.php on line 42
