So I've got a laptop running Pop! OS (20.04 LTS), I've just installed openssh-server via sudo apt-get install openssh-server and I'm attempting to SSH into it from my Windows 10 desktop PC but I get the following error:

Running ssh localhost directly on remote (I have the laptop in front of me) prompts me for password and then "connects" just fine.
I was able to scp the public key I wanted to use from my desktop to remote just fine as well.
Additionally, I am able to SSH from desktop to a completely different remote, my Macbook Pro.
I'm almost certain the issue is with the openssh-server installation on pop os but it's pretty much stock, I haven't run any additional commands beyond sudo systemctl stop/restart/status since installing it, and I was under the impression that this would work out of the box.
Any ideas what could be wrong?
