Events no longer have Publish option and not appearing in calendar

Hello!

I am having this exact issue https://wordpress.org/support/topic/events-changed-to-draft-after-last-update/

All the new events we are trying to add as being saved as Draft and do not have the option to publish.

I have turned off all caching and firewall plugins but that is not making a diferent.

Have Version 6.6.4.4.

Also get this message below but all the information is correct. We have correct date and time, featured image and description

Your event details are incorrect and cannot be published, please correct these errors first:

Something went wrong saving your event to the index table. Please inform a site administrator about this.

We have not had any issues like this before and all our events where fine. It seems to be an issue since the latest update.

Thanks

Ginnie
