To answer @Full30, I agree that topics don’t need to be closed so soon.
The topic that you mention was automatically closed because you marked a post as the Solution. For topics on Meta, they’re closed 30 days automatically after a solution is marked, because it’s assumed that the problem is solved and there’s no need for further discussion.
Other topics in wordpress remain open for months and years and so on.
I think it would make sense to ask moderators to reopen the original topic and merge your second topic there, since it turns out that your issue is still unresolved.
If @community-moderators could merge these two topics, and reopen the discussion, that would be helpful:
