Plugin causes php memory exhaust

Hi,

After one of the recent updates i’ve experienced that my site starts slowing down. I started to investigate plugins one-by-one, and it turned out the Product Configurator causes these symptoms, because when i disabled everything went ok. Here is the log from php:

PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 20480 bytes) in /scripts/env.php on line 437

PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 20480 bytes) in /wordpress/core/6.3/wp-includes/class-wp-fatal-error-handler.php on line 74

PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 20480 bytes) in /wordpress/core/6.3/wp-includes/functions.php on line 650

PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 20480 bytes) in /wordpress/core/6.3/wp-includes/plugin.php on line 482

I am using wordpress 6.3 with php 8.1.. My Product Configurator json file is 5.2Mb size, and i am using it for 10 different product on my site, if it makes sense for you.

Also when the plugin is enabled i got intermittent HTTP error 500 when visiting random page of my site. If i turn the plugin off, everything is ok site-wide.

Thanks for your help in advance!
