Until we get a permanent fix, you can trash all those bogus schedule actions in the SQL database by using this sql code in myphpadmin:
DELETE FROM ‘wp_actionscheduler_actions’ WHERE ‘status’ = ‘complete’
DELETE FROM ‘wp_actionscheduler_actions’ WHERE ‘status’ = ‘canceled’
DELETE FROM ‘wp_actionscheduler_actions’ WHERE ‘status’ = ‘failed
You can also delete all the logs that were created. There are probably thousands of them.
