Literally yesterday my 2022 Accountant version desktop started crashing during backup.  I tried several things and read as much of this blog as possible.  Nothing worked.  It only crashes during backups.  It starts the backup, gets to 99% and then Quickbooks disappears and the backup remains in unfinished mode. 

From what I read this problem has not been solved.  I don't have time and money to try and solve this problem. Thankfully it is only during backups that this crashes.  No idea why it started yesterday.  I have not updated anything and my last backup was only 3 days before.  So I had only entered a few transactions since then. So after spending over an hour trying to fix this myself last night, today I restored the 3 day old backup and re-entered the few transactions that were missing.  Did a backup and it worked.  So something in the company file since 2/3/23 has gone wrong and I think it is a Quickbooks issue since so many people with different  computers are having the same problem.  Thankfully I hope this never reoccurs.  I will be updating to 2023 soon and hope this problem doesn't resurface.  Disappointed to hear that Quickbooks has not fixed this problem.
