Totally been there. When I get stuck I sometimes use a Chat GPT tool to bounce ideas around. I'll give it a basic premise and see what kind of twists or character ideas it suggests. It's not about having it write for you, but it can really help jumpstart your own creativity when you're feeling stuck. I used one recently that you can find on this site
https://pr-cy.io/chat-gpt/ . Might be worth a try to get unstuck.
