External hard drive not showing in finder

I downloaded an app that changes the format of external hard drives from NTFS to something for Mac. However, I did not use the app and uninstalled it using app cleaner. Since then, my external hard drives do not show up in the finder's sidebar and I do not know how to reverse the problem and bring them back. The box for showing external hard drives is checked in the preferences. I have tried reconnecting the hard drive, using different hard drives, and restarting. Nothing has worked.

Mac mini, macOS 14.1

First, let me say that using 'other' apps to reformat external drives for Macs is often problematic. That is what Disk Utility is for and it does that just fine. Try restarting your Mac in the Safe Mode and see if that helps. If not, I think the problem is due to the original formatting, as I said. You may have to reformat the disk properly using Disk Utility to get it back.
