Move the keep() call after the callout. Code emitted after a branch isn't reached, as execution is transferred to the next block.

@oleavr
As you said, I've changed the code like this and this causes the target process to crash and nothing is printed is frida CLI:

I also tried to keep the first keep() and just add a second keep() after the callout and still the callout is not called but some log are printed in frida cli but it also trigger the target process to crash

I didn't mean to move it inside the if-block. That crashes because you're telling Stalker to skip all instructions except CALL instructions.

Code you emit before keep() is inserted before the instruction being kept, code you emit after gets inserted after the instruction being kept.
