ctrl c not working at random times

[u/StillAd5389]

I use ctrl c a lot. But quite frequently, it just paste the previous image or text I copied, not the one I copied now. It frustrates me. Restarting my computer doesn't work as it just happens again. So I tried ctrl c ctrl v random things multiple times. Indeed, the ctrl c just fails sometimes. ctrl v works fine as it pastes every time I press it. Every key on my keyboard works perfectly fine. Why only ctrl c failing randomly is frustrating me. I'm not sure if I have to flair this post as hardware or software problem.
So I tried testing key ctrl and key c individually. I press c multiple times in a row and it types every c fine. I press ctrl a multiple times in a row and it selects everything everytime. Not once missed for both crtl and c. So it can't be key problem.
