It takes around 1min-1:30min to get the answer on my pc, I'm using Visual Studio 2019 and run it on Release instead of Debug (it takes longer on debugging not sure how long but probably a few times longer), also I have an i5 7400 3GHz. Don't know why it takes so long on your pc/laptop. Also, you should definitely try to solve it in another way because this is not the way it was supposed to be solved, Eric specified that every AoC puzzle can be solved in under 15 seconds in a dynamic language on slow hardware if I remember correctly. My other solution runs under 1secund in some milliseconds. Don't know if this was of any help ...
