Resolved Whats a good way to do pathfinding?

I'm making a procedurally generated backrooms game that generates rooms as the player walks through other rooms, the map is huge, and only gets bigger over time as the player walks through it, so I'm thinking navmesh pathfinding would be slow, on top of that, I have no idea how to bake objects are run time. So I was wondering how I would code a pathfinding system that's good for my system, or find a good pathfinding asset from the asset store.

 

Maybe this will help ?
