Based on your feedback, you are experiencing the issue of deleting a printer and I can't add it back in
You can try the following:
You can try uninstalling the printer driver by going to the Device Manager or Control Panel program.
Then go to your printer's website, search for your printer model, and then download and install the printer driver again.
Then check again to see if your printer can be added to the device.
You can refer to the following link in the method of operation
