If a game has the same lines of code across all players, then why do some bugs only affect certain players?

Question

I was playing a game earlier when a friend was experiencing a bug. Wouldn’t it make sense for me to be experiencing the same bug since were playing the same game that’s coded with the same lines of code?

Let’s suppose that you like the color red, and I like the color blue. Therefore, you tend to dress your character in reds, whereas I tend to dress mine in blue.

Now let’s suppose that a dev wrote some code that caused an NPC to react slightly differently to someone wearing red, perhaps compliment the player on their color choice.

Now let’s suppose there is a bug in the code around that specific dialog.

Me, wearing mostly blue, would not trigger that dialog, and so I wouldn’t encounter the bug.

You, wearing at least some red, would trigger that dialog, so you would encounter the bug.
