You are focusing on the wrong things. You are so lucky to feel "empty". If you take some time to think about how hard people work just for a pittance, how they work physically demanding and mentally-stressing jobs that pay little to nothing, you can't help but be grateful for your situation.
And with the inevitable AI revolution just around the corner, many non-tech jobs (mostly all) will be obsolete. You will still have a job.
I think that is how it is for most software developers. Instead of dwelling on the unfulfilling aspects of your job, concentrate on your blessings, that you have a very in-demand and high paying job that requires very little effort to perform on your part.
Use your available mind power to work on your own projects on the side. So many people in the world don't have the opportunity that you do.
