Hello @burnout426,
I don't think it's something on @Gravity667 's end.
I have exactly the same issue- I can use Opera GX for around 5-10s and then it is unusable.
If you check this video, you can notice that many users have exactly the same issue as described in this thread:

The same story with people on Reddit:

The solution, that helped me it so go to C:\Users<username>\AppData\Roaming\Opera Software\Opera GX Stable and delete History file.
@Gravity667 let us know if it helps
