RC FAILSAFE after update 4.3.7

Good evening everyone,
I installed 4.3.7 for the first time on the Cube Orange (new) and I’m using Herelink 1.1
I always have the error of RC Failsafe and even after having calibrated the radio control, also “Radio Calibration” on Mission Planner died (no input).
Yet I have no doubt that the radio control works perfectly. For completeness of information Herelink is perfectly updated (both versions Airunit and Local coincide)
Can you tell me if version 4.3.7 provides a different setting or a particular qualification on the RC side?
Thank you
