Erro revSlider

Hey i did some research 

The error you are receving in your revolution slider is related to PHP 8.0 Compatibility. 

Fatal error: Uncaught ValueError: strrpos(): Argument #3 ($offset) must be contained in argument #1 ($haystack) in C:\xampp\htdocs\instituto\wp-content\plugins\revslider\includes\functions.class.php:387 Stack trace: #0 C:\xampp\htdocs\instituto\wp-content\plugins\revslider\includes\functions.class.php(387): strrpos('', '.', -1) #1 C:\xampp\htdocs\instituto\wp-content\plugins\revslider\includes\slide.class.php(2345): RevSliderFunctions->check_valid_image(false) #2 C:\xampp\htdocs\instituto\wp-content\plugins\revslider\includes\slider.class.php(2278): RevSliderSlide->get_overview_image_attributes('gallery') #3 C:\xampp\htdocs\instituto\wp-content\plugins\revslider\admin\includes\functions-admin.class.php(212): RevSliderSlider->get_overview_data(Object(RevSliderSlider), Array) #4 C:\xampp\htdocs\instituto\wp-content\plugins\revslider\admin\includes\functions-admin.class.php(128): RevSliderFunctionsAdmin->get_slider_overview() #5 C:\xampp\htdocs\instituto\wp-content\plugins\revslider\admin\views\header.php(11): RevSliderFunctionsAdmin->get_short_library() #6 C:\xampp\htdocs\instituto\wp-content\plugins\revslider\admin\revslider-admin.class.php(2209): require('C:\\xampp\\htdocs...') #7 C:\xampp\htdocs\instituto\wp-includes\class-wp-hook.php(287): RevSliderAdmin->display_admin_page('') #8 C:\xampp\htdocs\instituto\wp-includes\class-wp-hook.php(311): WP_Hook->apply_filters('', Array) #9 C:\xampp\htdocs\instituto\wp-includes\plugin.php(484): WP_Hook->do_action(Array) #10 C:\xampp\htdocs\instituto\wp-admin\admin.php(259): do_action('toplevel_page_r...') #11 {main} thrown in C:\xampp\htdocs\instituto\wp-content\plugins\revslider\includes\functions.class.php on line 387

I have checked and RevolutionSlider said they have added PHP 8.0 Compatibility please download the latest RevSlider plugin and try that if that do not work then you need to downgrade your PHP version untill the plugin Revolution Slider release the support for PHP 8.0 

Thanks.
