Hello,
Sorry for any inconvenience that might have been caused due to that.
It seems like new tables are not getting created in the Database or some old plugin has left an incorrect entry.
1. Please follow these steps to fix the issue:

2. Please follow only the first 2 steps and clear your caches. The following steps mentioned in the article are for advanced users.

Please clear all the cache, including the server after following the above process.
That should resolve the issue. Thank you.
I tried using the Repair Action Scheduler tool and it fixed the error, although not exactly in the manner described. The plugin did not automatically deactivate itself after the repair process. I had to manually do it.
Also I need to make sure that I do not delete the orphaned tables in WP-Optimize, otherwise the fatal error will be triggered again.
