Autoptimize conflict with admin access

Hi
The plugin Autoptize is causing page loading issues when trying to access the admin area of my WordPress site.

I troubleshooted with my host WPEngine and found that when the plugin is activated any of the pages in the admin area that I try to load keeps trying to reload and prevent me from using the admin area.

WP Engine support representative found a fairly similar problem here https://www.ads-software.com/support/topic/reloads-page-constantly/page/2/ , although this thread is about users using another plugin to automatically clear the cache within Autoptimize. I have a following code snippet that automatically clears autoptimize cache if it goes beyond 256MB.

// Automatically clear autoptimizeCache if it goes beyond 256MB
if (class_exists('autoptimizeCache')) {
    $myMaxSize = 256000; # You may change this value to lower like 100000 for 100MB if you have limited server space
    $statArr=autoptimizeCache::stats(); 
    $cacheSize=round($statArr[1]/1024);
    
    if ($cacheSize>$myMaxSize){
       autoptimizeCache::clearall();
       header("Refresh:0"); # Refresh the page so that autoptimize can create new cache files and it does breaks the page after clearall.
    }
}

Can you help me solve this issue so I can reactivate the plugin.

Thank you
Lyse
