Did you turn off crossplay? I have it enabled, sadly*, because the game is basically full-on singleplayer without it enabled. And that's not because there are no other PC players. It's because DE has made it so if you have crossplay disabled you won't match with anyone else except people who also went into the settings and disabled it.
*No shade to console owners/users, but you take longer to load on average, you don't spawn as many enemies to kill/loot when you host, and you're less likely to have a keyboard and be able to communicate quickly.
