Career Advice/RoadMap: Thinking to switch to Mobile Development from QA. Any roadmaps or advice in general?

30M here and currently working as a QA. My current ctc is 14LPA(6Y.O.E). Currently I'm on bench and looking out for projects. Parallelly I'm also looking outside, incase I don't get any projects in my current company.

The problem here is I'm not very good at writing programs(Or atleast that's what I think) and constantly face issues in programming questions in interviews. I have always been an A+ student, scoring in 90's throughout academics(Scored 100 in chem and phy in 12th). But never been able to clear programming interviews. This is affecting my self-confidence and I keep getting self doubts(One of my senior in my first company told me that, I'm good at theoretical concepts and I fail when it comes to the application of said concepts).

Now I'm into automation testing and as I was looking to switch, I kept seeing multiple openings for Mobile Development(Development in general, be it backend/front-end/full stack etc). The below reasons made me thinking as to why not switch to development:

1. My current CTC is low for my exp and testing usually don't have much openings
2. Testers don't have much respect in the Industry(Even from people working along with us)
3. Not much scope to earn more from testing field

My current thoughts:

1. Enroll into a Java course from any offline institute and learn Java thoroughly first.
2. Switch to a good company with decent pay
3. Invest time for 1-2 years and learn development and then try for some startups.

Any advice to my thoughts? Am I thinking in the right direction? And also, if anyone who has done this transition(Or similar transition) could shed some light on how you did it and what difficulties you faced, I would greatly appreciate it.
