Updated comment for Admins.
Began when installing 28.0. I revert back a few versions and issue persists.
I have not installed any utilities or browser extensions.
Does not make a difference if I use menu commands or hot keys, or if I use copy when right clicking and using pop up menu. I can make a copy of text by using Shift + Alt and dragging. But cannot copy something inside of Illustrator and then paste text into a new or existing field.
The only time I can paste into an existing field is when I copy from another program, ie excel. I cant copy something in Illustrator and paste into another program. Its like illustrator doesnt save things to the clipboard if it is text.
Sometimes I can make it work if I clear the clipboard in windows 10, but other times I cant. So it is really random.
Would like a solution because reverting to older versions or updating to newer versions does not fix the issue. I am having to change workflow and add extra steps. Restarting only helps sometimes and just for a few copy if that. Unclicking boxes in the clipboard preferences does not make any difference.

Lately among the adobe programs the copy and paste text is working. it still doesn't go if I copy and paste into word or crome or just into notepad

I have the same issue. I can copy and paste object or text that has been outlined but I cannot copy and paste editable text.

I have the same problem. Please do something Adobe. ITS ANNOYING AND I COMPROMISE MY WORKFLOW.

This often happen with text box (I have to outline everything and then the program allows me to copy and paste).

I have already tried several times with erase the clipboard and also with restore the preferences (Edition --> General). Those two methods sometimes work, but lately this bug got RANDOM and right now is happening again and nothing is working, I DONT WANT TO RESTART THE PROGRAM.

Again, ANNOYING AND IM PAYING FOR THIS!

hello Egor
no, I didn't install extensions utilities. the problem started from the installation of this latest version.
it makes no difference if i use the keyboard or the menu to copy and paste. The problem is only in the text because everything else (objects, images or other) copy and paste it without problem.
I can't copy text from Illustrator and paste it into other applications. From other applications to Illustrator does.
On first startup it works, then suddenly nothing more.
If you repeat copy from menu several times then paste.
I have disabled SVG Code

Vincenzo, please tell more. The problem is not new, happens sometimes for different users, but the cause of it is often different.
Have you installed any utilities or browser extensions recently?
Does it make any difference if you use menu commands for that or hotkeys?
Does it help if you copy several times in a row?
Are you able to copy and paste in other applications?
Does it help if you disable Include SVG Code option in Preferences > Clipboard Handling section?
