NDA prevents me from getting new job and I'm losing my mind

Quick background on my situation — any input appreciated.

NDA prevents me from getting new job. I've been dealing with this for about 14 months now and the situation isn't improving.

The contract was signed 18 months ago. I am not sure I have the original signed copy. The total amount in dispute is approximately $109,000.

What are the risks if I pursue this? What's the likely timeline?

I see this constantly on this sub.

I ended up filing with the appropriate government agency, which cost about $4-8 but saved me a lot more in the long run.
