Need advice for making fellow nerd friends

Hey! 26m, I am finally about to graduate college after failing to on my first try around and already landed a full time job about a month before graduation which is all amazing but one thing is really starting to dig at me. With this new work schedule I have along with moving out in about two months I am getting terrified of becoming alone. Most of the people I got to know in college are staying for another year or two to finish their degrees and I only moved to Spokane about 3 years ago so these friends are really all I have (Not many friends back at home either thanks to some nasty drama I won't talk about here, just one really close one.)

That leads me to my question; how do you make friends around here, especially other nerds? Honestly I am willing to try to get into different hobbies too in attempt to make friends like maybe some kind of TCG, heck some of my existing friends at college play DnD but tbh I have no clue how to play it.

At this point any kind of advice would be greatly appreciated. Thanks..!
