Copy and paste shortcuts not working on macOS Sonoma

Hi - please provide more information about the problem:

1. What keymap is used in the IDE? Preferences | Keymap
2. What is the actual key sequence that you press to execute the 'paste' operation?
3. Do you use IdeaVim plugin?
4. Are you able to paste the copied text into search boxes of dialogs, or do you only have this problem with pasting to the editor?

我只用了idea，当我进行复制的之后却不能将复制的东西粘贴到idea上面任何地方，但是当我切换到别的软件上，就可以使用粘贴的功能

1. What program on your Mac do you copy the text from?
2. Does it work if you use a mouse or touchpad to right-click -> paste?
3. Does it work if you use the shortcut Cmd+Shift+V to paste from history?
4. If you open Preferences | Keymap in the IDE (image below), click the 'Find Shortcut' button and press Cmd+V, do you see the shortcut mapped to the 'Paste' action? 

When searching for a shortcut (by using Find Shortcut) and using 

• command + c
• command + v
• command + <any key>
• …

is always

• command^

shown. See screenshot.

Hello,

Could you please provide information from “Help | About” (click on Copy and paste data here)?

After the update to IntelliJ IDEA 2023.2.2 (Ultimate Edition) the keymap is fine. 

IntelliJ IDEA 2020.2.4 (Ultimate Edition) is not working on macOS Sonoma for me.

Thanks for information! 2020 is pretty old and might have issues with newer OS versions.
