Two weeks ago, I deleted the desktop recycle bin when I playing the RocketDock. Now I want to bring it back but I found it's impossible to do it!
I have tried many ways but still did not find a good solution. Does anyone know what could be causing this? Any help would be greatly appreciated!

Oh, people do this always. easy to solve.

Right click "Desktop" - "Customize"

"Change Desktop Icons", and active "Recycle Bin"

Then your recycle bin icon will come back to your desktop again.
