Iphone Backup Problems on Mac

Hello- I have always, and refer to continue backing up my Iphone on my Mac mini rather than iCloud but recently began having trouble. I have a mac Mini running Sequoia 15.2 and Iphone 15 on IOS 18.2. When I am in finder on my Iphone and click Backup (Like I have done for many years) I now get "Cannot backup Iphone because the Iphone backup is corrupt". It says to delete backups, but for some reason it says I have none for this phone and says "last backup: Never" I have read everything I can but can't get it to work and have dug through as much of the Mac as I can looking for a backup folder to see if I can find a corupt backup file, but I can't find one.

The only major change has been updating to Sequoia so I feel like that has something to do with it but not sure. Any guidance is much appreciated. Thanks!

iPhone 15, iOS 18

Plug the iPhone into the Mac.

Open the iPhone in the Finder sidebar.

Select the General tab and click Manage Backups...

Highlight the iPhone backups and then click Delete Backup.

Make sure Backups: is set to "Back up all the data on the iPhone to this Mac"

Then select "Back Up Now" and/or "Sync" at the bottom of the panel to make a new backup.
