It needs more traffic (and that'll require better servers and more moderation with training to make sure that it doesn't follow the same arc) to become a standard place to go, but I've become fond of Codidact. If I remember correctly, the founder left Stack during one of their bigger moderation blow-ups.

There are lots of good alternatives, just nothing that mirrors Stack Overflow's goal exactly. Lemmy instances, subreddits, forums like code ranch, platforms like dev.to, etc.
