hi there , I think I have got a solution, the same problem was with me. I just simply tried to set opera as a default app from control panel rather than making it a a default app in settings . And it just worked on . still not then go to control panel set chrome/mozilla/edge as the default app (Control Panel\Programs\Default Programs\Set Default Programs) and click "set this program as default" , when other browser is set as default then set it to opera and you are done !!! Hope it works .. Thanks
