Hi there, GrumblePuss.

Thanks for reaching out for support here in the Community. I want to make sure you're able to use your QuickBooks Desktop account without it crashing.

In this case, I recommend running the Quick Fix My Program from the QuickBooks Tool Hub. If you haven't already, you'll need to download the Tool Hub first. Once you've done that:

1. Select Program Problems in the QuickBooks Tool Hub.

2. Choose Quick Fix my Program.
3. Start QuickBooks Desktop and open your data file.

The following article provides additional info on this process as well as other solutions: Fix issues when QuickBooks has stopped working

Please give this a try and let me know how things go afterward. I'll be here if you need assistance with anything else.
