@itzmaxxxx Only thing that i suggest you to do is to get the installation file and try repairing opera GX, its the only thing that comes to my mind.

I've fixed this like right now, i checked the time it took to crash and it took exactly 25.416 seconds for me to crash. i disabled all the extensions and it doesnt crash anymore. make sure that you dont have any extensions enabled (like i had an adblocker for youtube). if it doesnt work get the installation setup and run the repair option, it should fix everything
