How can I stop loaded program from running after debug or before program launch ?

Going from an input to output between builds means that a drive conflict could occur at next launch. If that happens I have found out the hard way that the part will not load.

Sorry, it is unclear to us what you mean. Can you explain in more detail what your problem actually is?

Depending upon your actual issues potentially useful FAQs might be:

Regaining debug access to target MCU

ISP Reset over debug

You might also want to look at the "Debugger Disconnect" behaviour setting in the Launch Configuration:

Launch Configuration Menu
