Fatal error: Uncaught Exception: Serialization of ‘Closure’ is not allowed

Hi there,

I ran into a problem trying to import products. In step 3, I linked all the data, but in step 4, I encountered this error (https://prnt.sc/utR2F4co-bX6):

Fatal error: Uncaught Exception: Serialization of 'Closure' is not allowed in /Users/BARN1/LocalSites/new-welldone/app/public/wp-includes/functions.php:625 Stack trace: #0 /Users/BARN1/LocalSites/new-welldone/app/public/wp-includes/functions.php(625): serialize(Object(PMXI_Import_Record)) #1 /Users/BARN1/LocalSites/new-welldone/app/public/wp-content/plugins/wp-all-import/classes/session.php(83): maybe_serialize(Object(PMXI_Import_Record)) #2 /Users/BARN1/LocalSites/new-welldone/app/public/wp-content/plugins/wp-all-import/controllers/admin/import.php(1611): PMXI_Session->set('import', Object(PMXI_Import_Record)) #3 /Users/BARN1/LocalSites/new-welldone/app/public/wp-content/plugins/wp-all-import/plugin.php(627): PMXI_Admin_Import->template() #4 /Users/BARN1/LocalSites/new-welldone/app/public/wp-includes/class-wp-hook.php(324): PMXI_Plugin->adminInit('') #5 /Users/BARN1/LocalSites/new-welldone/app/public/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters(NULL, Array) #6 /Users/BARN1/LocalSites/new-welldone/app/public/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #7 /Users/BARN1/LocalSites/new-welldone/app/public/wp-admin/admin.php(175): do_action('admin_init') #8 {main} thrown in /Users/BARN1/LocalSites/new-welldone/app/public/wp-includes/functions.php on line 625

I deactivated all plugins except for WooCommerce and both of your plugins – WP All Import and WP All Import – WooCommerce Add-On: https://prnt.sc/5-5e7NYi8dib

I also switched to the default WordPress theme (I tried both Twenty Twenty-Five and Storefront).

But nothing has helped.

Do you have any suggestions?
