Hi everyone.
Up to now i have been programming STM32 mcus at register level but i have to use cube mx now. So i created a cube mx project only to see if timer 2 works fine. When i build without any problems and run the code on my F303RE board and pause i see program pointer shows at the least function call before while(1) loop which in here is "HAL_TIM_PWM_Start" function. I didn't understand why this problem occured. Can anyone please help me? Below is my simple code. Thank you.

Going to have to debug it an understand why/where it stopped.
Check it is not in ErrorHandler() or HardFault_Handler()
Check it is not in Default_Handler() due to lack of interrupt handler for things you have enabled.

Than you for your answer @Community member. When i looked at disassembly to find where the program really is, i realized that it actually works in while(1), but in the C code window it shows the last function above while(1).

Most likely you have optimization flags set. Compiler code optimizations and C level line-by-line debugging are pretty much incompatible.

Yes @After Forever , i had made some changes in optimization settings on TrueStudio. After i load the default settings it worked.
Thank you for your answer.
