Help with removing board

[morta]

I need some serious help. Iv got to return my board and I can't seem to remove it. There is one screw stuck in the board that I can't remove. What tool do I need to remove this thing? Please provide links so I can buy the tool. I need this out asap!https://ibb.co/Mk2gNLf

My guess is the standoff is turning with the screw?

looked at the picture, wtf was the motherboard pushed through the standoff? (and that looks like a extra long one)
