Feeling Stuck in current job

It’s been 11 months since I joined my first job. Being from an IIT, I only did DSA in college and got this job paying a decent 20lpa base salary. But when I first joined here I was put at bench for the first 6 months. I always used to ask for work but got very vague work of writing python scripts. Finally I was put in a project but the work mostly involves utilising python and MATLAB. I have started doing DSA again and learning MERN stack. I am applying to a lot of jobs but apparently my resume is not getting shortlisted anywhere. I want to make this switch but my biggest fear is that if I will be able to get an offer which matches this salary. Any advice how to get out of this situation ?
