Debug mode not available

[VinnyAstro]

Hi there!

I am facing a problem I didn't have before: I cannot debug an executable anymore...

In the build specifications windows I:

• Enabled debugging
• Unchecked "Remove block diagram" in Source file setting tab.

Yet, I can't access the block diagram once the application is built.

Do you have any clue what could cause this?

Here are some picure of a very simple project showing my issue (also enclosed):

This is the .exe file window:

Thanks in advance for your help.

Vinny.
