Need help to restore precious photos from Time Machine backup

On My Cloud Home I have a Time Machine backup made on a Mac that was running Catalina. I am now running Big Sur on new Mac but need to get access to data on that backup because unfortunately I’ve recently lost a large directory of photos spanning more than four decades.

I’ve tried going into recovery mode but although the Mac can see the WD drive on the network when I select the Time Machine it can’t connect.

What are my options / the best way to proceed here please?
