Hello there, @cdhamer.

I've come with a solution that can help fix your QuickBooks Desktop Pro 2021 crashing issue.

There are some possible reasons why QuickBooks crashes while doing tasks or opening the company file. Here's a list of them:

• Your company name may be too long
• You may have a damaged or missing QBWUSER.INI file
• You may have corruption on your hard drive
• Your program files or QuickBooks Desktop installation may be damaged
• You may have a damaged Windows operating system

To get this resolved, let's run the Quick Fix my Program from the QuickBooks Tool Hub. This will help shut down any open background processes QuickBooks uses and run a quick repair on your program. Here's how:

1. Download and install the latest QuickBooks Tool Hub.
2. Once done, open the QuickBooks Tool Hub and select Program Problems.
3. Click Quick Fix my Program.
4. Start QuickBooks Desktop and open your data file.

If you get the same result, check out this article for more troubleshooting steps: Fix issues when QuickBooks has stopped working.

Please let me know how the troubleshooting steps go, @cdhamer. I'll be around to provide further assistance.

You may also want to run reports on QuickBooks Desktop. This will help review your transactions and business needs. 

Thanks for coming to the Community, wishing you continued success.
