Install

Hello there, @EGreco. I appreciate you for joining here.

You can follow the suggestions shared above, so you'll be able to work within QuickBooks without it crashing. 

Run your QuickBooks Desktop in administrator mode by clicking Books Desktop icon. Then, select Run as Administrator. Also, you can open a sample company file. Here's how:

1.  From the No Company Open window, select Open a sample file.
2. Select any sample file on the list.

If it persists, follow the steps of Solutions 3 to 5 in this article: QuickBooks Desktop doesn't start or won't open. 

Just in case, I'll add these articles for future reference:

• While working in QuickBooks, QuickBooks closes unexpectedly (crashes with or without an error).
• Fix data damage on your QuickBooks Desktop company file.

I want to make sure everything is taken care of for you, so please let me know if you have any other issues or concerns in the comment below. I'm always here to assist.
