I was trying to upgrade the FUS and wireless stack version on my STM32WB55 Nucleo board via ST-LINK using STM32CUBE Programmer GUI tool when I came to this issue. I first managed to delete the wireless stack by clicking on "Firmware Upgrade Service -> Firmware Delete" and it was successful.
After that, I tried performing a FUS upgrade with "stm32wb5x_FUS_fw_for_fus_0_5_3.bin", as acquired from Release .12.1: STM32CubeWB/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x at master · STMicroelectronics/STM32CubeWB · GitHub. However, it failed and gave me the following error information:

I have no idea how to fix this problem. Could anyone please advise or help? Thanks!
