Issue with following STM32WB MOOC Workshop 4: After enabling custom template CubeMX often hangs at code generation, and app_ble.c has error

[SWong.1]

Issue with following STM32WB MOOC Workshop 4: After enabling custom template CubeMX often hangs at code generation, and app_ble.c has error.

I have updated CubeMX to latest version (5.6.1), as well as the firmware package for the STM32WB55 (v1.6.0). Attached please see my IOC file and the app_ble.c file in question. These cause me not being able to compile the project.

Note: the code snippet start at line ~363 in attached app_ble.c file.

I know the MOOC material is outdated, but I was not expecting the CubeMX to freeze like this.
