Fatal error: call to undefined function

Users can no longer edit their custom PODS profile fields. This is the critical error email message (minus the stack trace) triggered by someone trying to edit their profile, and the PHP message seen on the user edit page and edit profile page when debugging is turned on:

Fatal error: Uncaught Error: Call to undefined function PMPro_Pods\Pods\tribe() in /home/marglotr2427/public_html/wp-content/plugins/pmpro-pods/src/Pods/Permissions.php:168

Latest WP version, all plugins up to date, PHP 7.4.

The PODS admin screens look normal, I can view and edit fields and groups.

Thanks in advance.
