A similar issue is occurring with me on 23.0.4(osx 10.14.5 mbp 2018 ). Opening a file creates a grey screen that locks me out of file editing or shows the previously opened file, but I may not interact with it. I may open multiple files and the tabs update to the file names but the first file is the only one that is visible. This happens randomly, but frequently. It's a similar issue to what was happening before, and has been happening since illustrator 23(osx) was launched. Illustrator does not lock I may interact with the menus, however I can't edit or properly see what file is being edited. It makes it difficult to save out files. Opening multiple files can sometimes trigger this issue as well.
Illustrator version 22 is not supported on macOS 10.14 (Mojave).
Please upgrade to version 23 to resolve the issue.
