Why moderators allow a question to be closed when no one actually answers the questions is another problem. Why people post an answer that is really "I don't know" ????

MacBook Pro 14″, macOS 15.6

Interesting! Thank you for posting this.

Regarding your final question: "why..." we can only guess, especially since you did not post a link to that other thread; but usually threads are closed when there is no activity for some time. Say I ask a question and nobody replies for a long while. The thread is basically "dead" so it makes sense to me that it gets closed.

I think the OP did include a link to the original thread: Force excel to open in new instance by de… - Apple Community

But your explanation as to why threads are sometimes closed is spot on.
