Trying to install the latest Arduino Create Agent after downloading from the site (https://create.arduino.cc/getting-started/plugin/install) on the latest Catalina. The installer just bounces in the dock and says it isn't responding. As an attempted workaround, I can right-click, Show Package Contents, navigate to Contents, MacOS, and open osx-x86_64, which does actually get the installer to "stick" in the dock as running, but it still doesn't actually open any windows, and continues to say it isn't responding.
Does anyone have any suggestions? (I have re-downloaded, rebooted, checked that there is nothing showing in System Preferences -> Security/Privacy, etc.)
