I am able to copy text from other programs and paste it to Android Studio. I am able to right click and copy selected text. I am able to cut text and paste it using shortcut. But while using shortcut Ctrl + C to copy text I am often unable to copy. This is very annoying problem. Does anyone here knows how to solve it?
If restarting AS does not resolve the issue you could try Invalidate Caches/Restart option. That sometimes fixes such issues.
----update----
This might fix your issue.
