Hi AA20IP,
I am Dave, I will help you with this.
This is a common problem when you are programming in Windows 10, create a new folder on your Desktop or somewhere else on your PC, then inside that create a folder for each of your programming projects.
Then in Defender, add that parent folder that contains all the programming projects to the Exclusion list
Then, Defender will not scan your newly created executables.
How to add the folder to the Exclusion list
