Errors with WooCommerce and Mailpoet

Since I cleaned articles, comments, options and terms, Mailpoet doesn’t work anymore. I get this message on Mailpoet page: Syntax error or access violation: 1142 INSERT command denied to user ‘xxx’@’infongp-es6.clienthosting.eu’ for table ‘wp_mailpoet_scheduled_tasks’
More, there’ a fatal error with WooCommerce (Uncaught RuntimeException) with table ‘wp_actionscheduler_actions’ and ./plugins/woocommerce/packages/action-scheduler/classes/migration/ActionScheduler_DBStoreMigrator.php
Now I don’t have access to Mailpoet and I can’t activate WooCommerce.
And now navigation in the admin of the site is very slow. It seems there’s a problem of request with the db. But no speed problem in the frontend.

Any idea of the problem? I can sent the whole alert messages if necessary.
