Since I can't read the entire error message, I will have to guess that that image is already in Lightroom. Check your already imported images to see if it is already there. If it is a different image with the same name, try renaming one of them.
Also, you seem to be using "Lightroom", the web based app. This forum is for "Lightroom Classic" a different application. There is a separate forum for "Lightroom".
Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Past that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.
