No ADB devices connected

No ADB devices connected. I keep refreshing, restarting and double checking cables but still I cannot Build my Unity project to my Quest 3. The Windows 10 PC states that the Quest 3 is connected via USB. I had this working 6 months ago but now I simply cannot connect. I wish to run my Unity game on the Quest 3. Any advice or help pages most appreciated.
