Thanks for reaching out to the Community, PortMike.
Since QuickBooks is crashing when you switch to single user mode, I'd recommend making sure your books are up-to-date with their latest release.
Here's how:
- In the top menu bar, go to Help, then Update QuickBooks Desktop.
- Choose Update Now and click Get Updates.
- Once your update finishes, close and reopen QuickBooks.
- When asked to install the update, select Yes.
- Allow your installation to complete, then follow the on-screen instructions.
If you're already up-to-date, or updating didn't change anything for you, you can troubleshoot with our QuickBooks Tool Hub.
Here's how:
- Close QuickBooks and download a copy of the utility's most recent version, then run it.
- Follow along with your on-screen steps to complete installation and agree with our terms and conditions.
- Once it's installed, double-click its icon to open the tool hub. If you can't find your app, perform a search in Windows for "QuickBooks Tool Hub" and select the program.
- Access your Company File Issues tab and use the Quick Fix my file and QuickBooks File Doctor tools to troubleshoot your company file. In the event you need additional assistance, choose File Dr Help.
If your books continue crashing while switching to single user mode, you'll want to get in touch with our Customer Care team. They'll be able to pull up the account in a secure environment, conduct further research, and create an investigation ticket if necessary.
I've also included a detailed resource about QuickBooks crashing which may come in handy moving forward: While working in QuickBooks, QuickBooks closes unexpectedly (crashes with or without an error)
