 * Hello.
 * Can you check if this table really doesn’t exist? Maybe you changed the database
   prefix?

 * Last I found the error is database cache . I used redis for object cache and 
   after I removed plugin wp_rio_process_queue table is deleted but Robin plugin
   debug still read the database cache and saw wp_rio_process_queue exist so the
   plugin stop creating the wp_rio_process_queue table . Anyway to update Migrations
   code to bypass database cache in the furture? If I click the import button in
   clearfy setting the robin plguin start Migrations form 1.1.5 to 1.4.2 and solved
   the problem too .
 * I found 2 ways to solve this problem , use only 1 of two is completely solve 
   the problem.
 * 1/ Go to clearfy setting and click import setting ( Can you tell me did clearfy
   flush object cache when clicking import buttonm or doing anything about request
   robin do all Migrations and old Migrations codes have the clear object cache 
   feature? )
 * 2/ Flush object cache and robin plugin processed like 1st method

 * Using the object cache, you should understand that this can lead to similar problems.
   You can also disable all caching plugins before updating Robin.
 * We will try to solve this in future updates
