Ask HN: I have a solution, how to find a problem?

As part of my master's I developed a model that can connect code to business logic and understand the why and what behind the code, and even translate it to simple English.

I want to build a product around it and been trying to find what problem this model can solve. I am aware that this is the opposite of the recommended advice of 1st finding a problem and then build a solution. - I tried to talk to my fellow programmer friends and ask them about their process of writing and reading code but didn't find any strong problem that can be solved with this model. - I built a simple MVP that takes a new assigned ticket with a task and predicts what files are needed to be changed to accomplish the task in the ticket, I published it in some forums and put some ads on Google, but didn't get any paying customers.

How can I find a good problem that my solution will solve, and have a good product-market-fit and high value?
