Bug Report (Although the Plugin is Very Good)

Hi ,

First of all, i have to say the plugin is world-class and every serious developer should have on in their tool kit.

Everything work fine, except that the bug that i would like to report:

Testing Enviroment

1. WordPress 6.8.1
2. PHP 8.2
3. All Plugins deactivated except
   • Microthemer
   • Code Snippet Pro

What i have Tested

1. To test if the CSS modified by Microthemer will still keep after i deactivated the Plugin

What i have done

1. Copy and pasted the following Code Snippet (based on the Plugin Suggestion) in to the function.php of my WordPress via Code Snippet Pro

/* Begin Microthemer Code */
if (!defined('MT_IS_ACTIVE')) {
$file = ABSPATH . 'wp-content/micro-themes/AssetLoad.php'; // modify this for WP multisite

// Load MT AssetLoad class if it's available, and hasn't been loaded yet
if (!class_exists('\Microthemer\AssetLoad') && file_exists($file)){
    require_once $file;
    new Microthemer\AssetLoad(true);
}
}
/* End Microthemer Code */

Result after

1. The Code Snippet is activated, AND

1. The Microthemer Plugin is deactivated

Result i got in my website:

There has been a critical error on this website.

Please suggest
