email invitations

My zoom has gone crazy. First, when I schedule a meeting and save it to my Google calendar, I get an option to send out email invites. This used to work fine when I just entered the email of the person(s) being invited. NOW, it lists all the emails of those who are invited to future meetings and sends out invitations to everyone! Mortified! I've tried to delete those addresses but then it deletes their scheduled meetings too! So I uninstalled and reinstalled. Nothing. I tried to connect again with the Google calendar and it's telling me "Add failed, the calendar-related access permissions are not allowed." HELP! I'm running a business here and this is so frustrating!
