Debug ToughGFX generated code

I generated code using ToughGFX 4.13.0 for the STM32F769I_DISCO board. I was able to run target in ToughGFX and import the code into the CubeIDE. There were missing files that needed to be deleted from the project to get it to build.

But after that, I can't load the debugger. I get the following in the console:

And the following in the error dialog:
