Addition of Synced Folders crashed app on Monterey

I had been using this on High Sierra with 4 or 5 defined Synced Folders in preference for some time. Moved to a Monterey machine and PutIOSync will crash when I attempt to add more than one Synced Folder definition.

I was able to copy `putiosync.storedata`* files from the old machine to the Monterey machine and it sort of works.
