Just installed 2022  two weeks ago and this is happening to me as well. I open a QB file and it buffers a minute and shuts down. Sometimes, it shuts down two times in a row. Other times, the file will open, but as soon as you click on an app/icon to do whatever task, it shuts down. I have to re-open it. There is something going on here. How do I fix this? So frustrating!
