STM32WB55 FUS Corrupted in a reset

Hello,

I'm having problems with the FUS not starting and the Wireless stack not responding.

In my code, the wireless stack can be updated. In the process of updating it, the STM32WB55 was interrupted by an external reset, and the FUS was left unresponsive.

These are the option bytes:

I tried to reenable the FUS by following these steps: Unable to start FUS. FUS version is 0.0.0.0 and FUS_STATE_ERR_UNKNOWN 

Since most of the things mentioned looked almost the same. I attempted to toggle the RDP to BB apply it and back to AA, and momentarily it looked like it worked, but when I tried to update the wireless stack afterwards, it failed again and I wasnt able to make it work again.

Any help is appreciated.
