The suggestion not to use a short term release like 23.10 is good advice for use on a primary system. The only reasons for going to a short term release would be if something does not work on the current system and you have good reason to believe it will on the new release. Updating it shortly after its release often leads to problems but in any case, I would suggest as above to stick with LTS releases.
I'm also curious as to why you have an ntfs filesystem on your backup drives. If you don't have windows and don't share with windows there should not be a need or use for windows filesystems. The problem you get when you do this is the possibility that the filesystem gets corrupted and you have no way to repair it. You need windows software to do that, for example running chkdsk /f from windows on the filesystem. You should be able to get windows as a free download or some windows repair software to do this. The fsck and ntfsfix options available for ntfs filesystems are extremely limited compared to the actual windows software chkdsk.
Since, if I understand your post, you still have earlier versions of Ubuntu, prior to 23.10 installed and are able to access those foreign filesystems (ntfs) on your external drives with them there would be no point in reinstalling 23.10. I don't know what the problem might be if that is the case as I don't use short term releases.
