I am trying to do revisions to drawings for a client today and am getting a message, "Error Loading Plugins. DxfDwgFileFormat.aip". I click the Okay button, Illustrator opens up, but I cannot open ANY Illustrator files AT ALL. Client is NOT going to be happy. Illustrator updated a couple days ago (in the background, unbeknownst to me). I am running version 26.3.1. Also, I am on Mac OS Mojave 10.14.6. I have no idea what's going on, it was working fine yesterday. I haven't changed anything. Why is this doing this?
