Problems with copy/paste in Illustrator on Windows

I've been there and tried it all...like yourself. 

Are you using Logitec devices and have their software installed? If so, try ending the process. 

If that is the solution to your problem, you can either A) delete their software. ( your hardware will still work in a basic way ) or B Create a .bat file that ends the process for you:

@2846721 off
echo Attempting to stop Logi Options+ processes...
taskkill /F /IM logioptionsplus_agent.exe /T 2>nul
echo.
exit

I do the latter, and keep the .bat file on my desktop. When copy and paste doesn't work, a quick double click will end Logitec Options and copy and paste will work. 

It's frustrating, good luck.

I am experiencing severe and increasingly worsening copy/paste issues in Adobe Illustrator. Copying and cutting works, but pasting fails almost every time, making normal work impossible. I have tried everything: resetting preferences, restarting Illustrator, using the toolbar buttons instead of shortcuts, disabling GPU performance, testing with and without plugins (Overlord uninstalled), clearing caches, testing scaling and high-DPI monitors, reinstalling Illustrator via Creative Cloud, and even trying older versions. None of these solutions have improved the problem. This issue is persistent and escalating, and it completely prevents reliable workflow. I need a solution, as this behavior is not normal.

In Windiws 11 there are several clipboard related settings that "enhance" the clipboard. Can you turn them off?
