Help, Effectively Bricked my Giga R1

Short Version:
The solution to my problem is this: I need to erase the Arduino Gigas Memory.
I don't know how to do that, if you do, can you help me out

Long Version:
I loaded micro python onto my Giga. While creating code for an LED matrix I managed to write some python code to the Gigas memory that will not allow it to operate as anything else other then my blinking light. [I wrote it on the file labeled boot.py instead of the Main.py in the usb memory that pops up when you plug it in after installing Micro python]

I am still able to burn the boot file and put on different versions of Micro Python, however the file is not getting cleared when I burn the boot. I assume because that does not erase that memory.

I assume I can erase it with some C++ code in the original load. However I do not know how to do that.

Reflashing it with micro python makes it where the com port does not show up in the IDE, Assume because that boot file is what allows it to be seen and accessed by windows and the IDE.

Can someone please help me out with a solution to clearing the memory on this Giga board. I believe it is the Flash memory that i need to clear but I am looking on the data sheet and it looks like there is also some SD ram and Nor flash memory. I am not sure what exactly needs to be erased or how to erase it. I will continue trying to fix this but maybe you guys could help me out faster.

Alright, well I have tried many things now and I am still in the exact same boat.

I used the program STM32CubeProgrammer to erase the internal flash memory... I think

but all of my problems still remain.

My guess is that there is some more memory on this Giga that I don't know how to get to. I have flashed this thing many many times and in many different ways. However as soon as I reapply micro python, I am back in the exact same boat.

The boat of the com port being in accessible and the device running the python code i created as opposed to its normal boot code.

I have no access to the gigas memory through windows any more. Before when I would plug it in a storage device would appear like a flash drive. However I can no longer get to that.

Loaded a new DFU file. This allowed me to get to the mass storage space again. I am not sure exactly what happened. Maybe somehow I wrote my code onto the DFU file... I really dont know what the heck I did.

However loading a different DFU was the solution for me.
