Hello this is a fresh build and for some reason even know my reciver and transmitter are binded together  I have no stick input in the receiver section in betaflight .. The reciver RX is connectedto the TX on the fc and and the Reciver TX is connected to the RX on the fc .... . I've added the dump and diff file .... Any help would be greatly appreciated

Your Betaflight settings all look fine, assuming of course that the Nano RX Pro is wired to UART1.

Please post some good clear photos of the actual wiring and connections between your receiver and flight controller.

Here is the image and yeah my reciver is on uart 1

The wiring all looks to be correct. Use a multimeter in continuity (beep) mode to make sure that you don't have a short circuit between any two of the 5V, GND, RX1 and TX1 pads on the FC.

Also, run the TBS Agent Lite LUA script on your transmitter and check in the Output Map section that CH1 is set to CRSF TX and CH2 is set to CRSF RX.

I would also update the FC firmware to Betaflight 4.3.2 because there were some bugs in earlier versions of 4.3.x, so updating to the latest available version of 4.3.x will eliminate anything which might be causing some issues.

Okay I did everything you suggested and and everything checks out... Is it possible that even know i have a solid green bind lights that my reciver went bad ? Even know this is a fresh build I have had this TBS Nano rx pro receive soldered onto 4 other Flight Controllers .... I'm thinking I should just order a new one

Examine both sides of the circuit board of the Nano RX Pro with a magnifying glass to see if any components are obviously missing or loose. It's a known problem that components can be dislodged from some of the Crossfire receivers, especially the ones that are right on the edge of the circuit board.

   I don’t see any shorts but it wouldn’t hurt to reflow the yellow solder joint.
  It could be a cold solder joint.

I want to thank you both for taking the time to help me...  After doing everything you both suggested and nothing fixing the issue I went ahead and put my receiver on Uart 2 and i have full stick response...
I then reached out to tech support at getfpv and after doing a few things they suggested they determined that Uart 1 was faulty.... They are issuing a exchange..... Again thank you for all the help....

In order not to create a new topic, I'll ask here. Does this module heat up a lot? I want to print a case for it, but I'm afraid it won't overheat in a closed space? Do I need to make any vents in such a case?

It will probably be fine in an enclosed case but if you want to put it in a mount I would personally advise that you leave the top of the mount open. So create and print a "tray" rather than a fully enclosed case.

I made a case with holes in the front, stream should be blown a module , that's placed in a heat shrink.
