I FINALLY solved it and the main thing is from @bridges. I must say you must look back at 2021 if you any sort of idea on what to do. All I’d say, is by now, you have the grid and the partial decrypt. Maybe look at each of the pairs that decrypt correctly, and find what is common about them, then find what is common between the incorrect ones – maybe then you’ll see a way they could be correct. Then your final step is to code a solution.
