you're facing a video playback issue specific to Opera on YouTube. To resolve this, try clearing your browser cache, disabling hardware acceleration (Settings > Advanced > System), and updating Opera to the latest version. You can also disable any extensions to rule out conflicts and test the video in a private window (Ctrl+Shift+N) to check if the issue is related to cached data or extensions. If the issue persists, temporarily disabling antivirus software or reinstalling Opera might help fix any underlying problems.
