Troubleshooting File Sharing Permissions:

I. Be Logged In as the Administrator:

Are you logged in as the administrator? Be logged into it, for a better chance to use File Sharing.

II. Reinstall the macOS:

Anything that has been corrupted (i.e. File Sharing operability on your macOS) would be (A.)replaced or (B.)relocated to their original location.

1. First, Back up your Mac:

Create a Time Machine backup of your Mac, so that you can have something to restore your Mac from, should anything go wrong with the reinstall.

2. Then, Reinstall the macOS:

Nothing would be deleted. It's just that items that have become corrupted or deleted, would be replaced or reinstalled back to where they should be. Go Here: How to reinstall macOS from macOS Recovery - Apple Support

"Catalina 10.15.7 and sharing files: [...]Above all it’s an USB external drive (named “The hard drive”) that I cannot share. The permissions are NOT changeable. The next stop is to move its content into another drive, reformat it (it’s Exfat now) whith APFS[...]"

The Format is the Culprit...

Purchase and Use a Pre-Formatted Drive:

Your macOS only reads AFPS format. Your hard drive is formatted of ExFAT, which is for a Windows PC. So, what you need to do is purchase an external hard drive that comes pre-formatted to work with macOS and Windows. You'd plug both hard drives into the Windows PC, and would then transfer it from this ExFAT drive, over to pre-formatted macOS/Windows drive. Being you are now using a perforated Mac/Windows external Hard Drive, all data would be accessible between both the Mac and the Windows PC. Data transfer would work and transfer like a charm.

IMPORTANT: Just don't format the new external Hard Drive to be macOS or Windows-only, prior to all of this. And, look at the original packing to make sure it is compatible with both Operating Systems.
