Unable to open project after C++ conversion attempt

Hi there,

I am new to the C++ side of Unreal Engine 5 and I’m using 5.1 at the moment.

I followed these instructions to convert my projects from Blueprint to C++ and now I’m not able to open the project in Unreal Editor at all:

Can anyone help me out to figure out how to get the project to open again?

Thanks so much!
