In google chrome when I highlight a word and right click to select 'search google' or 'search youtube' the tab pops for a millisecond then disappears. Works in Edge not Chrome. I have updated chrome and turned off all extensions one by one. Hardware acceleration settings.
Since disabling the extensions and updating the web browser didn't help, can you please try uninstalling Google Chrome, Downloading Its Installer, and installing it afresh?
If even that doesn't work, please try scanning your PC with an efficient antivirus program, and running any free PC optimization tool like Ccleaner or Ashampoo WinOptimizer and see any of those could rectify the issue.
Feel free to report back if any further assistance is needed.
