Product Warranty Dispute: NDA prevents me from getting new job

Using a throwaway bc my boss knows my main. I've been trying to resolve this on my own but I'm stuck.

NDA prevents me from getting new job. I've been dealing with this for about 9 months now and the situation isn't improving.

The contract was signed 8 months ago. I have a copy of the original agreement. The total amount in dispute is approximately $15,000.

What's the typical outcome in situations like this?

I went through almost the exact same thing.

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