In that example, this programme can be correctly flashed to the micro:bit V2: https://makecode.microbit.org/_9KKHE4WyyUM3 microbit-largeSwitch.hex.zip

But the programme goes all the way in flash up to address 0x752B0, writing to flash memory areas reserved for CODAL storage usage and Nordic SDK BLE bond data: https://github.com/lancaster-university/codal-microbit-v2/blob/master/docs/MemoryMap.md

A programme that doesn't use CODAL storage nor BLE will probably not trigger a problem, but a soon as those features are used it can cause issues.
