I was coding with nucleo f401re board in stm32cubeide. However, I found a problem with timer not working properly when iwdg is enabled in ioc settings. Do you know a solution to this?

The IWDG should have no effect on the timers unless the watchdog causes a reset, in which case the timers, along with almost everything else, will be reset. What problem are you seeing?

Regardless of the prescaler and period values ​​that I have set, the time value created by the timer is displayed at will.

How are you determining the timer value is wrong? Can you post a minimal working example showing the problem?
