This is happening for us in QB Desktop Accountant Enterprise.  We are actually considering switching our entire practice away from Quickbooks because of this behavior.

When selecting employees in the employee center, QuickBooks will freeze.  It is NOT a particular employee causing the issues.  I have made several calls to support, opened tickets, etc.  I have gone through all the repair steps, downloaded all the tools.... nothing helps.  This is CLEARLY a programmatic issue.  I have invited support people / developers online to see the behavior themselves, they have declined (which I don't understand).   We have noticed this behavior from QB 2016 to QB 2019.  It's our firm opinion that Intuit has broken it's own software, and because of our multiple support tickets and no response or fix, they don't care.

I'm posting this as a last-ditch effort in hopes that SOMEONE will help me, come online with me, view my screen, see the behavior.   It is NOT company file specific.  It is happening with ALL of our QB files, and is happening on ALL computers in our company.
