I'm having the exact same issue, and I've spent a total of 5 hours on the phone with support who finally told me they don't know how to fix it. Everything was fine until I had to upgrade QB 2019, and QB 2022 wouldn't recognize my computer as having a 64-bit processor even though it does. The workaround was installing QB Pro Plus 2021 and deleting QB 2022. It hasn't worked right from installation, and now it just loads then crashes, loads then crashes. The only thing that works occasionally, is installing all the updates (as recommended somewhere in these forums), then restarting, and if I'm lucky, it might load all the way and allow me to do some work. Once I close QB, I have to start all over again. Can't anyone fix this?
