Same here and I have been on hold with support waiting to chat for over an hour with no response. 

Hello there, Isabella and HBController. I'd like to ask for more information about the problem you experienced.
 

May I know which window or page you were on in QuickBooks when the error message appeared? Providing additional details or a screenshot would be appreciated. This way, I can address and offer an accurate solution.
 

I look forward to your response, Isabella and HBController. I'll be here to respond promptly.

I was under a member/customer and clicking edit invoice/pledge. As soon as I click "edit" this is what I see. 

Thanks for getting back to us, HBController.
