Programmer for 20 years, burned out twice, how do I keep working?

I have been programming for 20 years. After the first 10 I burned out and had to switch to contracting for a couple of years before I could get another FT job.

10 years later it happened again. I believe i had covid early on in the pandemic but i was never tested. I was working from home and the company I was with didnt care at all about its employees well being. I had a plethora of health issues and my performance dipped so they fired me after 2 years.

The next job i took was for a start up as vp of eng. I had to quit after 8 months when

1. I could see the signs of burning out 2. The owner fired all my engineers, crippled my hiring process, wouldnt give me a budget, and i had to pick up all the slack and work from 3am to 7pm seven days a week and recieved absolutely no recognition for it 3. I found out the owner was plotting to replace me with a friend of his and demote me after i had saved them from losing a multi million dollar contract and sacrificing my health to do it

I took the last 7 months off and worked on personal non paying side projects. Now i need to get back to work so i dont run out of cash.

I had originally planned to do some contracting again, but i dont even know how to land contracts these days (10 years ago i was just getting them via referrals).

Any advice on what type of job to look for that wont drive me insane and rob me of my health? Im a very skilled programmer but cant stand the thought of re-entering the nightmarish world i have been away from. I have already applied to about 20 start ups but am absolutely terrified im going to find myself in the same situation i was in with my last two jobs.
