We use MAC Desktop 2016 and suddenly a couple months ago QB began crashing every time we tried to open it. It all started after trying to convert an estimate to an invoice. Eventually we had to restore an old backup and re-enter al the transactions to that point. Everything was working okay until today. After doing a lot of work and entering many transactions the the program crashed and I'm back to the point where it won't open at all like a few months ago.
I should note that I've got the most current R upgrade running Version: V17.2.32 R33.
