Good news for macOS users who are on Illustrator 2021! Adobe backported a fix made for the compatibility issue to its latest long-term support version Illustrator 2021 (v25.4.5), which is now available on the Adobe Creative Cloud desktop application for download. If you choose to update your Illustrator to version 25.4.5, please remember to reinstall ArcGIS Maps for Adobe afterward. You can download the latest version of the application from here.
For more information about the supported environment, please refer to https://doc.arcgis.com/en/maps-for-adobecc/install/requirements.htm.
