I'm an accountant and my client is using QB 2020. Another is using QB 2019 and it is also crashing. Both only started crashing when I installed the latest update, my guess is from the payroll tax update but that is just a guess. No, I absolutely cannot force all of my 2019 and 2020 clients to the QB 2021 version. That is most definitely NOT a solution for me. I will keep searching for a posted response I can use and I have sent the error reports repeatedly to QB with no response. This is truly unacceptable for Intuit.
