I followed this[1] URL to update FUS and wireless stack, it failed and now i can't get wireless to work. All the examples are hard faulting. My FUS is still in version 0.5.3

Or is it possible to flash the original wireless stack that came with the board?

Fixed this by first erasing all sectors from the "Erasing and programming" section of the programmer GUI and then flashing the FUS by

STM32_Programmer_CLI -c port=usb1 -fwupgrade stm32wb5x_FUS_fw_1_0_2.bin 0x080EC000 firstinstall=0
