Work for Hire Dispute: NFT of someone else's art

Using a throwaway bc my boss knows my main. Looking for advice on a legal issue. Here's what happened.

NFT of someone else's art. I've been dealing with this for about 9 weeks now and the situation isn't improving.

This involves software/code I developed over the past 33 months. I do have documentation proving my ownership and timeline.

Has anyone been through something similar? What worked for you?

This happened to me too. Have you tried filing a complaint with teh relevant agency? In my case they investigated and it got resolved without needing a lawyer honestly.
