Looking for help from anyone who can…

I am the owner of a recurring meeting. It started in April and ends in
December. I want to change the recurrence starting in July. Can I do
that now without impacting the dates before July?

No, because a recurring meeting is just a single entry in the calendar.
Copy the appointment to another appointment on the same day, open the first
series to add an end date, then open the second series to add a new start
date and whatever recurrence changes you need.
