If you want to become a dev via this route, right now that is a risky move and a long road to real expertise that would carry you through an economic downturn where very junior people are let go. If it is your passion to be a dev, maybe, but expect it to be difficult. Maybe just consider going back to a proper university for that CS degree you probably should have gotten to begin with?
If you want to become a much better PM and have the tools to start building apps on your own, then yes DO IT! Right now the economy is great, if in 3mo you are back on the job market saying "I'm an awesome PM and I did a coding bootcamp to increase my understanding of the products I manage so I can be an even better collaborator" you will just have increased your value significantly. Probably you could just go back to your old job with a promotion.
