Running MacOS Catalina 10.15.7. Downloaded 5.2.2, copied it to the Applications folder. Right clicked on it and selected open, confirmed that I wanted to run it. Confirmed again after the OS checked it. Then it disappears out of the force quit window. If I try and start art again it immediately disappears. If I delete the application and copy it over again from the dmg it goes through the process again. Any ideas on this? Thanks
