Illustrator 2020 (v24.0.2) crashes consistently with "Can't Finish Previewing"
At a random point, it switches to outline mode, and then a dialog box opens and states, "Cannot finish previewing". Thought this was fixed in previous releases but since updating Ai its happening again.
Same here, it suddenly began happening when I made the mistake of switching to 2020. It's become a Chinese fire drill at work to constantly revert, delete preferences, and play whack-a-mole with Illustrator problems. In this instance I have found that when I drag a JPG from Messages on Mac into Illustrator, it gives this error. Then I can't revert or switch from line mode, nor can I save the doc. So it's a death sentence for the document.
At this juncture I do not expect Adobe to fix these issues, they are simply falling so far behind on bugs that they can only address the most glaringly obvious problems—most of which are breaking their programs with increasingly common updates. It's unfortunate because so many of our careers rely on this software, but I'd be lying if I said I'm not looking for the first exit off this sinking ship when the opportunity presents itself.
