St-link debugging launch to main failed

[Preedish]

I am running into a frustrating issue while trying to debug my project. Whenever I start a debugging session, the debugger fails to hit or start from the main () function. 

I have already double-checked and configured the settings under Tools > Options > Debugger [adjust path if necessary], but the issue persists. Because of this, it's extremely difficult to step through the code and understand the execution flow from the beginning. 
Environment Details 

• IDE / Version: IAR EW 9.20.2 

• Language: C/C++ touch GFX framework is there  

• Operating System: Windows 

• STM32H750IBTx 

What I've Tried 

1. Checked and re-configured the debugger paths under Tools > Options > Debugger. 

2. Cleaned and rebuilt the solution/project. 

3. Kept breakpoint one the very first line of code after main () 

Error Message / Behavior 

• The execution does not stop in main () entirely or throws a symbol loading error.

Check that the correct ELF/OUT file and debug configuration are being used, and disable optimization for the debug build. Also verify that symbols are loaded correctly and that the MCU startup code reaches main(). A breakpoint in the reset/startup code can help confirm where execution stops.

There is quite a bit happening before an application reaches main().
Have you tried to set a breakpoint at the reset vector entry ?
In some IDEs, this amounts to unmark a “Run to main” setting for the debugger.
