When it comes to breaking out of ruts, I encourage all of my students to 1) listen to other players critically and 2) learn new vocab. I will help students learn licks, chord voicings, rhythmic ideas, etc from their favorite players/songs and then learn to process that info using the CAGED system so that it can be used in any key or tempo. Learning new vocabulary on your instrument will help you start to have more options when you go to create. The reason I sound the way I do on the guitar is through the same process: hundreds of hours of carefully listening, learning, and workshopping ideas that my favorite players played, singers sang, or writers wrote and working to make it a part of my vocabulary that I can access at any time.
