after testing around I found out that it was a combination of the phone 'Samsung S22 Ultra' (Yes it is updated to the latest firmware) and the Micro USB to USB cable.
I tried the cable with three different drones and saw that it was the same on...
The communication path from the drone to the mobile device go ... Drone <--> RC <--> Mobile device.
The message on your last pic. says (RC not connected to mobile device)
This likely means that the connection works Drone <--> RC... but fails...
This will very likely not work... DJI jacked up the anti rollback value one notch between these 2 versions, this is probably why a downgrade possibility doesn't exist in DJI Assistant 2.
And how do you determine that... does your drone flip over when you try to take off?
Have you made sure that you have attached all prop blades correctly & on the correct motor?
As a reference...
