max_questions error in error_log

When using WP Forms Lite on a WP5.7 installation at Bluehost shared hosting, getting a repeated error that I suspect is from WP Forms:

[08-Apr-2021 17:45:55 UTC] WordPress database error User 'xxx' has exceeded the 'max_questions' resource (current value: 1) for query 
SELECT a.action_id FROM wp_actionscheduler_actions a 
WHERE a.hook='wpforms_process_entry_emails_meta_cleanup' 
AND a.status='pending' 
ORDER BY scheduled_date_gmt ASC LIMIT 1
 made by require('wp-blog-header.php'), require_once('wp-load.php'), 
require_once('wp-config.php'), require_once('wp-settings.php'),
 do_action('init'), WP_Hook->do_action, WP_Hook->apply_filters, 
WPForms\WPForms->WPForms\{closure}, WPForms\Tasks\Tasks->init, WPForms\Tasks\Actions\EntryEmailsMetaCleanupTask->__construct, WPForms\Tasks\Actions\EntryEmailsMetaCleanupTask->init, 
as_next_scheduled_action, ActionScheduler_DBStore->find_action

Talking with support at Bluehost they increased the memory for PHP in .htaccess using hp_value memory_limit 2048M but that doesn’t really help. Since this is shared hosting I don’t think I can change the max_questions setting.
