Could a failing High Endurance microSDXC Card (256GB, V30/U3) cause the 70MAI A810 to have symptom: Dash Cam Sd Card Format Loop?

The A810 requires high-endurance NAND flash capable of sustained 4K video write speeds. Standard SD cards often enter a permanent 'read-only' protection mode once their write-cycle limit is reached or when they cannot clear the 'dirty bit' on the file system due to high-latency controller responses. Replacing the media with a V30-rated endurance card designed for constant overwrite cycles resolves the communication timeout between the dash cam's processor and the storage controller.
