I have unrecoverable errors building on STM32CubeIDE a project generated by STM32CubeMX.
The errors arise compiling assembly .s sources for ThreadX.
Versions:
STM32CubeMX 6.17.0
STM32CubeIDE 2.1.0
Error (excerpt from build console):

I have attached the .ioc file.
The project name can be misleading, the target is NUCLEO-L496ZG board, which has a 144-pin microcontroller.
