Thank you so much for your responses. I figured out the problem. I did not try discord, but I think it was related to permissions, even though this is a new Mac and I'm the only user. I discovered that when I tried to show test files in the finder, there was now response. Then I tried searching for them, and the did not show up. I'm not sure where AppGameKit was creating the files, but whereever it was, it was not working. I fixed it by manually deciding where it would create files, the desktop for test purposes. Now it works fine. Again, thank you for indulging a newby!
