There’s a bug in my system (NSFW SPIDER)

After crawling under my desk to plug in my HDMI cable, just about had a heart attack & whacked my head against my desk after discovering this critter on my GPU. Any debug suggestions appreciated, i’d like to sleep care free tonight! (Seriously I have no idea how to get him out & I do not want to pop open the glass panel)
