Hello PadrePedro
It may seem that this is a device registration issue coming from some BT adapters in Windows 11.
Then run:
WinSxS folder cleanup: https://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/clean-up-the-winsxs-folder?view=windows-11
Repair windows image: https://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/repair-a-windows-image?view=windows-11
Then
Please install the latest drivers for your BT adapter, then run Windows update to ensure you have the latest patches.

Update 2: files can be sent to the "old" devices. For example, when my smartphone isn't paired, I see my smartphone listed twice in the wizard (only in the wizard, nowhere else). When I pair my smartphone it's listed three times. Sending a file to each of them works, so they're all effectively referring to the same smartphone. I still have no idea how to clean this up. Probably the 2 extra instances are coming from an image, so it's probably some piece of "history".
