I chose to stop caring about things like that. Some people just suck at organizing things, don't think of it, or don't have time for it. So I take the lead (or did, moved just before COVID and don't have as large a social circle here yet). I'd invite people to my place, or convince the friend with the pool at their house to host but do all the legwork organizing it (inviting, getting people to bring food and drinks), just declare "I'm going to be at on Friday, they've got a live band, and there's a concert around the corner I'm going to check out later on."
And I was pretty indiscriminate with invites. If you were a friend, you got an invite. A coworker who was not an asshole, you got an invite. New person I met at the gym or on the soccer field and liked, you got an invite. Neighbor I saw in the hallway, you got an invite. This is part of what helped me develop a large social circle. Throwing an invite to an event to 30-40 people + their partners who I may not have known beforehand, you'll get takers most of the time. And if you don't, you have fun anyways.
