Documentation, GitHub issues, language forums, reddit. Nowadays it seems more often that those resources help me work around the issues I'm encountering rather than stackoverflow. There are also the AI tools that help me easily get answers to the question "how do I do X in language/framework Y"
Not OP, but I’ve been trying to formulate problems in ways that first principles and primary sources (language docs, etc) can answer. It’s more work but also more rewarding and a better learning experience for me.
