How this relates to #12952 - if its fixed, will this be as well or what issue is reported here?

Could we close this one as well (like #12952) ?

at application starts, erasing one sector 4k.
it takes time...
I suppose at the same time BLE starts and erasing sector interrupts the BLE startup.
BLE get stuck - no connection afterwards.

You definitively have to try master branch...
