Recurring Events Disappeared?

I have lost my ability to work with recurring events. It seems to be a conflict with the Toolset plugin. I have also reached out to their support.

The recurring events I had created still have their individual events.
The Recurring Events submenu is gone, so I can’t see a list of my recurring events. It’s gone as an my +New… to add a new recurring event. And in the events list, it no longer shows an event was part of an existing recurring event with a way to detach the individual event or edit the recurring event.

So basically, I’m stuck with the existing recurring events as they are and cannot add any more.

I have reached out to Toolset Support (https://toolset.com/forums/topic/conflict-with-events-manager-their-recurring-event-type-disappears/). But if anyone has any insight, it would be appreciated.
