Unexpected perspective

The other day, when we started the game, an issue occurred where the camera became fixed at a specific location and stopped moving entirely. Upon investigation, we found that while the player object was moving, the camera was failing to follow it.

Compared to the version that works correctly, no scripts or similar elements were altered; we had merely added or moved objects within the scene. Upon sequentially disabling the added objects, we discovered that a specific object was the cause.

We imported a free asset for that object, but it turned out to include a camera inside the model. Since we had never encountered an asset like that before, it led to this issue.
