MissionPlanner is stuck at Getting Params after trying to connect to RFD900x

#### Issue details
Hi Guys, I have flashed and tried with latest ardupilot firmware of plane and copter in Cube Orange+, I have connected one RFD900x with Cube with TELEMETRY 1 Port, and given 5V power supply from external source, another RFD900x is connected to the PC with FTDI. RFD900x is also flashed with latest firmware(3.57) and hardware is V2.0 .
I have checked all the TX,RX Cables everything is connected fine.

When I open MissionPlanner and go to Optional Hardware -> SiK Radio and then I click on the load settings I am able to see all the parameters of the remote and local RFD900x device as shown in the below image.


After this when I try to connect COM6, with the baud rate 115200. I get connected but then while getting the parameters Mission Planner is stuck at getting params as shown below, although I am able to see HUD Parameters changing like, altitude, yaw, vertical speed, etc.


#### Things that I tried

I have tried these multiple things for the resolution of these issue but no luck :

Changed baud rate to 115200 and air speed to 200.
Changed baud rate to 57600and air speed to 64.
Changed baud rate to 9600 and air speed to 64.

I was also changing parameters like **SERIAL1_BAUD** to 115, 57 and 9, **SERIAL1_PROTOCOL** is 2 (MAVLink2), **SERIAL1_OPTIONS** is set to 0.

I tried changing Mavlink to standard and low latency both.
I tried changing MAX WINDOW to 131,80 and 20.
RTSCTS and ECC is untick.

I also tried interchanging both the RFD900x but still no luck.

#### Version
MissionPlanner 1.3.79 as you can see in above image.

#### Platform

Please provide your possible resolution for this, Thanks.

Start by reviewing the attached mission planner logs.txt and reproducing the connection with MissionPlanner 1.3.79, a Cube Orange+, and the RFD900x pair at the reported serial settings. Trace the connection flow until parameter loading stalls; done means identifying a reproducible cause and restoring completion of parameter loading, or documenting the confirmed hardware or configuration dependency.
