at least for me, writer's block occurs when i feel like i've exhausted thoughts, ideas, motifs, etc. that used to fuel creative output previously – but changing your perspective (either by changing your influences, or your environment, etc.) will put more gas in your tank to write new, exciting things, and to experiment with how you write about those things
in the artist's way, julia cameron mentions how a core tenant of the program is "artist dates" where you go out on a solo excursion to give yourself more creative "input" like novel life experiences, new perspectives on familiar experiences, etc. that can then funnel into creative output
i think a similar effort is just reading more; for example, i like sci-fi as a consumer, but when i was reading parable of the sower by octavia butler for a book club, i was so inspired by it that previous projects in that genre i had parked because they felt uninspired became exciting to work on again. new sci-fi projects came to me and gave me some runway to outline / draft them. same for fantasy, non-fiction, etc
the more you're inspired (either by your experiences or your influences) the easier it will be to write more, because exploration will often take less effort than refinement. both are essential parts of the process, but if you're exclusively refining based on a body of work limited in scope, it's going to take more time / be more agonizing / feel less worth it; if you can expand that scope, there'll always be something to say on the page
