Removing obsolete or incorrect addresses from Calendar (autofill)

I made a typo and once typed (my own email incorrectly) into a Mac Calendar entry and now every time I attempt to enter the correct email address Calendar autofills the invitee name with the errant email address. I typed myname@gmail.con, instead of myname@gmail.com. Of course, the gmail.con goes nowhere.

It happens when I open a new calendar invite, start typing my name... and boom: it autofills with the incorrect email address. So, if I'm not extra diligent I'll invite a non-existent/typo person.

I've attempted to "remove all recent locations and attendees" from the Calendar>Preferences>Advanced settings, to no avail. I have checked by Contacts. I have restarted. I have checked my Mail>Previous--- in fact, this error is located ONLY on Calendar.

Anyone solve this problem? (macOS Sequoia, 15.3.2)
