Bit Banding issue

[rsoli.1]

I have an issue with using bit banding on stm32U575ZI-Q board 

when I want to write on it Hard fault is appear what is the problem and How to overcome this issue?

Bit-banding is only in Cortex-M3 and Cortex-M4, so no bit-banding in STM32LU5xx which is based on Cortex-M33.

Show the actual code (disassembly) and registers where it's actually failing, might shed some light on why..
