Hello @vd3 

First, Could you please try using the STM32CubeProgrammer V2.21.0 and the .bin files for stack and FUS from the STM32CubeWB V1.24.0. First, use the automatic selection of the start address (available on the last version of the STM32CubeProgrammer). Also, upgrade your FUS Version to the V2.2.0 using the stm32wb5x_FUS_fw.bin available on the STM32CubeWB V1.24.0. After that upgrade the stack you are looking for from the same version of the CubeWB using the automatic address feature.

Best Regards.
