Need help finding the name of this movie

Alright so it's about this guy who's trying to prove this creature exists the whole movie and no one believes him. From what I remember, it only comes at night. At the end the creature shows up, it jumps through the window while he has his estranged wife and a couple friends over for dinner. It was kinda like an 'I told you so' moment for the main character right before the creature kills him. The creature walked on all 4 from what I remember. Sorry if the details are vague, as I only saw the movie once a few years ago. It was recommended on one of the streaming services but I cant remember which one. I was just thinking about this movie the other day and can't find any info when I try to look up the details online. I'm hoping the reddit community can come through on this one.
