But this started around Quicken for Mac 6 or 7 and MacOS 15. I've excluded the quicken file from AV scanner (ESET) and it still happens.
I've been dealing with this problem for a few years now where periodically I'll get an error about having to relaunch because of difficulties with the file.
It seems to be one account that has transactions going back to 2011 and its always a record in 2017. When I reconcile its off. I find the transaction by exporting a backup to CSV and comparing the differences between that last known good backup and the export of the current file.
Sometimes its a few days or even a few weeks and then it happens again.
