It's pretty unusual to have the burn thread crash like that, it means there's some sort of memory access issue.
The log/screenshot don't really give anything away that would help me figure out exactly where this is happening.
Whilst it could be an nvidia driver thing, it's not erroring out in the same way for you that it does for other people.
If I'm to try and help any more, the best thing you could do now is try using one of the other I/O interfaces and see if the same thing happens. After that I'll probably have to send you a debug build to try.
btw, you don't need to restart to eject the disc, just load ImgBurn again and tell it to eject it (it'll unlock the tray before doing so).
