"Cannot attach to application" when running Rainbow Six: Siege through GPA

[_MaZ_]

Title.

The game has two .exe files, tried both of them already at least 10 times. I tried a 2014 and this year's version of GPA, none work.

When I run the automatic detection and run the game through the GPA, I get a message saying "Cannot attach to application" and I cannot open the HUD nor anything. Same with the previous things.
