Most religions specifically dissuade people from thinking critically. I recall my time in my Jesuit high school, where any questioning of the tenets were frowned upon.
The basic concept of faith is to accept something which can’t be proven. It is antithetical to critical thought.
I have spent years learning about religions of the world, as I recover from my religious trauma. There are very few which truly encourage critical thought.
I started an all-trans punk band online, and my usual music is singer-songriter. The new project really pushed me, and turns music making into a social activity! I also started another solo project that is 100% cello covers of contemporary songs (last one I did was “girls just wanna have fun”). Both of these projects push me out of my usual, and breathe some fresh air into my music. Maybe you could find some ideas that pushes you out of your comfort zone?
