After trying to paste what turned out to be a very large variable into a new DG file and seeing the spinning multi-color pizza for a few minutes, I force-quite DG. Since then I cannot open the program–nothing but spinning pizza. I have restarted the computer and reinstalled the software (5.4 on a Mac running OS 15.1.1), and the problem persists. After first force-quit it reopened the several windows that I had open; I was able to close them over the course of several minutes. But I still can’t use DG. What else do I need to delete to get use back?
