I mean the obvious answer, given that this is HN, is that you should make it yourself. A basic text forum in PHP wouldn't be super difficult.
But practically speaking, and unfortunately, hosted forums are a dead technology. All of the attention is on social media, Discord and federated solutions like Mastodon and Lemmy. If what you actually want to do is create a community rather than write software, you could consider existing solutions like that.
