This might've been discussed here before, but seriously how does one make new friends in this city?

I recently turned 30. Moved here over 5 years ago. All the friends I made are through work and a non profit organization that went to shit. My friends either moved out or have kids and don't have time to socialize. Covid years messed me up and the only 'friend' I had was my ex. Now I live in a big house with my dog and a roommate that works odd hours. I work from home mostly. It's depressing. I looked into meetups. I'm not picky by any means but most of them suck, aren't for my demographic, or outright creepy. Tried to pick up a hobby or two to just get out of the house. People are great like many of them in the city but they're all preoccupied with their own life. Austin feels like home to me but I feel very isolated and lost. I'm not a total introvert and I get along with strangers well enough.

My real question would be, how did people in their 30s with a busy-ish life successfully made friends recently that aren't childhood buddies or coworkers? This happens in most major cities but are there any Austin specific events or activities where you get to meet new people and potentially build acquaintances or friendships? TIA
