On nucleo_u575zi_q below observations has been captured.
Issue: - when IWDGRSTF flag is cleared by writing to the RMVF bit still watchdog reset occurred.
Expected Behavior: - When the IWDGRSTF flag is cleared by writing to the RMVF bit, the watchdog reset should not occur.
Please find the below snippet of sample code of STM32cubeIDE.
Also find the reference of user Manul and data sheet of nucleo_u575zi_q board.
Please provide appropriate solution for the above issue.

Why do you expect such a behavior ?
Nowhere is stated that any access to said flag will stop the IWDG.

To halt IWDG during debug, set DBG_IWDG_STOP in DBGMCU_APB1LFZR.
