How do I handle title issue discovered after closing?

I'm in a difficult situation and trying to figure out my next steps.

title issue discovered after closing. I've been dealing with this for about 16 months now and the situation isn't improving.

Am I overthinking this or is this a real legal issue worth pursuing?

I went through almost the exact same thing.

I ended up hiring an attorney to send the initial letter, which cost about $2-4 but saved me a lot more in the long run.
