Hello @awstanek,

Thank you for joining the thread here in the Community space. I'm here to assist you with your concern about the crashing problem in QuickBooks Desktop.

As of now, there's no confirmation from our backend team if the new update is causing the issue. Since you've previously contacted support and the problem persists, I recommend you continue working with our QuickBooks Support Team (follow my steps above to reach out to them).

You can provide your case number to the next representative to streamline the process. This way, you no longer need to explain the issue repeatedly.

There are additional steps they can provide that are unavailable in this public forum. If all else fails, they can take the necessary actions to get you back on track.

If you notice possible data issue, or you've done the research and suspect data damage, perform some troubleshooting steps. I've attached a link you can visit for more information about the recommended solutions: Fix data damage on your QuickBooks Desktop company file.
