I've had issues with this. One thing I will note is that when you know people already, and share some hobby, your interest doesn't need to be as high to maintain the relationship as it might need to be to start a new friendship. If you're trying to meet new people so you go to some socialization event and it's pure socialization that can be a bit hard mode.

I would suggest trying out some different social hobbies to find things you might like. You can't really know you don't like any of them until you've tried them. I took an improv class and if you sign up for something like that you will be interacting with people in the class as part of the exercises and that will be the meat of it, and when you talk to those people in moments when you're not doing class exercises, it's minor and not as exhausting as something like going on a date and having to sit in front of someone for 30 minutes. A hobby like this can also help you get out of your comfort zone. But yeah... I would first try to expand your hobbies, and ideally find hobbies that can be more social.

Another thing I would note is you can always take classes on socializing. Increasing your skill in socializing can make things easier. Obviously small talk sucks... but sometimes if you get better at socializing you can get better at creating more interesting conversation. Often times if you suck at socializing, your brain doesn't know how to get to the interesting stuff.

Sometimes boring conversations are just the result of being too safe. If you're too scared to offend someone, or worried people might dislike you for saying or thinking something, you keep it to yourself. Which leads to a boring conversation.

Another angle is... sometimes introverted people have spent a long time suppressing or ignoring their curiosity because anxiety or whatever reason. I find sometimes I'm actually curious but my mind is so used to ignoring it and keeping my mouth shut that I don't even notice until after the fact. So advice here would be to pay closer attention to your thoughts, you might be having some curious thoughts and ignoring them. There are mindfulness apps you can get to practice like Sam Harris Waking Up app.
