wpml bug /error

Since a few days I noticed those errors :

must be an array or an object that implements Countable in /home/xxxs/public_html/wp-content/plugins/gdpr-framework/src/Modules/WPML/WPML.php on line 81

Warning: session_start(): Cannot start session when headers already sent in /home/xxx/public_html/wp-content/plugins/sitepress-multilingual-cms/inc/wp-nav-menus/menus-sync.php on line 47

Warning: Cannot modify header information - headers already sent by (output started at /home/xxx/public_html/wp-content/plugins/gdpr-framework/src/Modules/WPML/WPML.php:81) in /home/enquetesprivees/public_html/wp-admin/includes/misc.php on line 1126

As soon I deactivate your plugin there are no more errors…
WPML, wordpress, divi theme and your pulugin are all updated
Thanks a lot for your help and nice plugin!
