I’m afraid to change job

Guys, at the moment, I’m working as a DevOps professional at the same company for one year and nine months. During this time, I’ve learned a lot, but I feel like I’m stuck right now. I don’t feel very happy with the current tech stack, and there are some aspects of leadership that I don’t like. I’m a Junior DevOps, but in my role, I’ve never worked exclusively on ‘Junior-level’ tasks—I just do what needs to be done. Do you think I should change jobs? I’d appreciate advice from people with more experience.
