I had the same issue with Perfect Dark when I played it as a kid. Me and my brother were stuck in the Skedar Ruins level forever. We just couldn’t figure out to proceed, and it was before we had Internet access, so we had no way to figure it out.

I’m not sure we ever finished the game.

That said, I still have some of my most treasured gaming memories from that game and it’s predecessor, Golden Eye 007.
