OK, I think I know what happened
OK, I think I know what happened! So when we try to attach a debugger to the process the game quits instanlty.
But no error from GG occurs. Meaning, the anti debugger thingy is from the AVA.exe process itself!
And what we need to do is crack it.
I know I got it. But it's hard to crack exe files. Needs to know assembler.
