Invalid Meeting ID from Google Calendar

My recurring meeting ID on one of my meetings is suddenly invalid. This is a meeting I host twice a month. January, the meeting link was fine. I cancelled the meeting occurrence earlier this month, but on yesterday's meeting, I clicked on my link as usual from my Google calendar and when it popped out into the browser, I got an "Invalid Meeting ID" message. I have other recurring meetings that seem to work fine--this is the only one where this happened.
