I don't know where you live, but a lot of brick & mortar board game stores either run session, or know who do. Also, there 's a chronic lack of (good) DMs. If you're willing to DM then finding players should not be hard.

I'm way too socially awkward to try and join a new group and none of my friends are interested in any sort of ttrpg so I just started playing solo D&D. Once you get into the habit of using solo tables it's pretty fun. The Solo Adventurer's Toolbox is a great book for trying it out, I just wish I could find something on the same level for other rulesets.
