When i try to submit solution or the code choosing a file, it shows "Please complete the anti-bot verification" so i go to submit section and then give the problem serial number and then submit

I am facing this problem couple of months, ive tried using different internet connection, other methods i found in internet but didn't work, facing difficulty solving problems cause i have to manually submit the code everytime

How to solve this problem? and what's the reason causing this problem?
