Pixhawk 4 RC Input Spikes

Dear Community,

I am facing a decent problem. My drone, became almost uncontrollable, because of weired RC-Inputs.
My setup:
PX4 v1.8.2
Frysky x8r (S-Bus)
Taranix X9D

Situation: I am using this setup for almost 1 year without any bigger issues. But last week the drone received or interpret strange RC-Inputs, which you can see in the logs. It changed the flight modes rapadly and randomly. Same for the other channels, like pitch, roll,yaw,kill switch… I don’t know if I am facing the same problem as other users.
I think it might be a serios security issue. Please let me know what you think. I can’t reproduce the problem.
