Yeah this is still happening on 2020 and 2019

Same problem on Illustrator 2020, after rotate line

Same problem.

same problem !

same issue! ㅠㅠ

Error when creating a new document.

How can I go back to Ai 2018 since 2019 is not working, can somebody tell me?

same issue, Ai 2019 is not responding, I contacted Adobe support, they uninstalled and installed App but still with same problem, not responding

Same issue. All menu items are greyed out and can't use shortcuts. I have to force quit and lose my artwork.

Running iMac OS 10.14.6, 32 GB DDR3 with over a terabyte of available hard drive space. 27-inch iMac at 2560 x 1440. Never had any problem until today.

It did seem to start after I clicked on the graphic styles panel which I had docked. Had a file open, clicked on it, and that was the last thing I was able to do.

I closed the graphic styles panel and created a new workspace. This seems to have stopped the issue of all menus being grayed out (disabled) like there is an open dialog box. But it's only been a few days.

This also seems to be related to a message that pops up sometimes "There is not enough memory to process the appearance of an object". Is this the dialog box that is disabling all my menus but I can't see it?

Experiencing same issue

I have this same issue, upon the first launch of Illustrator 2019 all menus are grayed out (disabled) like there is an open dialog box or something. I have to force quit to get Illustrator to quit. On the second launch, it usually works okay. I am running Mac OS 10.14.5.

Same problem here. I can't open any ai files by adobe ai 2019 today. My OS is win10 home 64bit.

I was able to overcome the problem. First, I uninstalled it via the Creative Cloud app. When I went to re-install it, it showed it was still installed! So I uninstalled it again. Because I had Illus 18 still installed, it showed I could "update" it, which I did. Upon launching the updated v19 it did not have the grayed out menus. However, I did not change my workspace but I'm not going to, because it's not necessary. I hope this helps somebody.

I just hit an accidental hotkey that did the same thing. I don't know what I turned on, when I am in the menus on the top of the screen the cursor is automatically in "search" in the help menu.

Obviously, it doesn't appear to be a high priority bug.

Same issue. It's like a dialog box is open somewhere , I can't see it and I can't close it (tried ESC and Enter).

Same issue!

Dominic: I've received no reply on this. I've switched back to 2018 version for now.
