I have the same problem. I’ll use the camera on looping mode for several bike rides, but at some point it inevitably stops working - flashing alternating red and orange. When I look at the SD card it’s full (which shouldn’t happen with looping mode, ever) and about half of the video files are corrupted. Only formatting works. On the road, it’s impossible to format the cards though. I have to carry extras with. It’s a deal breaker, I’m shopping for a new camera - but very few seem to make cameras ready for use as dashcams for bicycles. Body worn cameras look more promising.
