Post Grid Master – plugin activation triggering fatal error

After update Post Grid Master plugin caused a critical error and took our website down. I was able to deactivate the plugin and get our site back up but our theme requires this plugin and as you might imagine some of the pages look a bit janky without it. I was unable to re-activate it due to the following error:

[15-Jul-2024 06:41:55 UTC] PHP Fatal error: Uncaught Error: Failed opening required ‘/home1/wqawigmy/public_html/wp-content/plugins/ajax-filter-posts/inc/functions.php’ (include_path=’.:/opt/cpanel/ea-php82/root/usr/share/pear’) in /home1/wqawigmy/public_html/wp-content/plugins/ajax-filter-posts/ajax-filter-posts.php:94 Stack trace: #0 /home1/wqawigmy/public_html/wp-includes/class-wp-hook.php(324): GridMasterPlugin->init_plugin(”) #1 /home1/wqawigmy/public_html/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters(NULL, Array) #2 /home1/wqawigmy/public_html/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #3 /home1/wqawigmy/public_html/wp-settings.php(550): do_action(‘plugins_loaded’) #4 /home1/wqawigmy/public_html/wp-config.php(101): require_once(‘/home1/wqawigmy…’) #5 /home1/wqawigmy/public_html/wp-load.php(50): require_once(‘/home1/wqawigmy…’) #6 /home1/wqawigmy/public_html/wp-blog-header.php(13): require_once(‘/home1/wqawigmy…’) #7 /home1/wqawigmy/public_html/index.php(17): require(‘/home1/wqawigmy…’) #8 {main} thrown in /home1/wqawigmy/public_html/wp-content/plugins/ajax-filter-posts/ajax-filter-posts.php on line 94

I have also tried deleting and re-installing but I am still unable to activate it due to missing files. It appears that the folder is empty under “/inc”

Some help to get this plugin functional again would be much appreciated
