I have a 2020 rav4 hybrid, brand new C4 installed with open pilot. Inconsistent reliability. The car is fine one moment, driving with open pilot engaged. and sometimes it disengages and dash alerts start popping up and the camera screen displays messages from "take over vehicle immediately" to "Vehicle variant Unrecognized" . What could be the problem, and is there a solution? Also flashing back to stock didn't work, it won't pop up as a device at all on my laptop. and I have reset the device multiple times.
