I'm having the same problem and getting the same error message in Mac Plus 2022 Desktop. I can open 3 of my company files, but the one that I use merchant services in will not open. Very frustrating. Wish Intuit would have alerted us (Mac users) that there was a problem so that 1: I skipped the update and 2: didn't spend two days invoicing. 

Any updates on the fix or guidance from QB would be greatly appreciated.
