It happened while I was running the game. How do I fix this?

Seems like you destroyed the shared mesh used by a MeshCollider right before instantiating it, since the error is complaining that the sharedMesh in the collider is null (we use it as index in a dictionary during the collider's Awake() to get a reference to its unmanaged counterpart if it exists)
Can you give a bit of context? (what are you trying to achieve in your game? are you using any custom scripts that might affect colliders?)

Thank you. I just want to click the button and show it. I made a new rope. Fortunately, it didn't make a mistake again.
