The thing is, 0x0000…00 is not followable to a source because it’s invalid- it means it’s looking for something… Nowhere?
There are a lot of solutions on this thread that helped others- give it a shot!

Whoa, that’s crazy. I’ve never seen anything like that before.
What are your computer specs?

Hello all. This is happening because of the Smooth Motion enabled in the Nvidia App (Global Settings options).
To solve it, open the Nvidia App and in the Graphics window, restore the Global Settings to default again.
Cheers.
