If you've already got significant savings, you can either use the runway to launch your own startup or even just buy an already profitable business that makes enough money to pay for your living expenses.
I'm not sure I'd suggest switching to a different job if you hate all of the bullshit around corporate programming because you'll probably hate all of the bullshit around whatever other job you pivot into as well. If you own the company, you can choose to just not do all of that agile/waterfall/scrum/whatever bullshit and to build whatever you want built assuming you can make enough revenue or investor funding from it to make it financially viable.
[0]: If you truly hate your job and/or insist on looking anyway, I'd recommend looking until you burn out on job interviews and dealing with the rampant spam and fake jobs polluting the job boards. If you get an offer worth accepting before that, that means you've won the lottery. If you don't, stop your search until the market improves or you feel like trying it again. My own experience being forced into a job search in this market against my will[1] has strengthened my own resolve to get the hell out of employment so that I don't ever have to deal with job interviews ever again.
[1]: Specifically, I was laid off from a great job that I was very happy at where there was very minimal corporate bullshit to worry about because their client cancelled a project that I was supposed to be working on. The company didn't have anything else for me to do.
