It might help to try and build a fun project in your new language, and only you can gauge your confidence level, but here's a possible way to at least take a stab at some interviews. For jobs in the new stack, perhaps send a version of your resume to emphasize your accomplishments and using the right tool for the job rather than using a particular tech stack for a particular project. If you currently have something like this in your resume: "In Company A, I led efforts to scale their website from 10,000 to 5 million users in Node.js." Maybe change it to this. "In Company A, I led efforts to scale their website from 10,000 to 5 million users". That might get your foot in the door for an interview. Then it just becomes a matter of proving you know your stuff in whatever interview you get.
