How, exactly, did you try to open it?

What CubeIDE & CubeMX versions are you using?

What is your Host platform?

The message says that the problem is probably due to an "abnormal previous IDE session exit" - is that the case?

If so, did you try closing everything and restarting the computer?

In addition, you are welcome to upload the IOC here and we will be happy to check it for consistency and completeness - it may have been damaged beforehand.

I change the file. But now, I have anathor question. The file I use is one of the example on stm32G431RB "DAC_SignalGeneration2" and for this example, the output frequency on Oscillo is 1kHz but for my use, I want to have high frequency for sinusoidal signal on oscilloscope. I try many issu but i don't have what i want.

For example, I calculated PSC et ARR corresponding to my frequency i want or double the number of step in tab sinewave or do (programmed a specific tab sinwave at the frequency i want but i stil don't have good result on oscilloscope. 

And i don't understand the specific roles of each timer (TIM2 & TIM6) in this code.

Thank you for you respond
