Failure to detect pressed key

Yes, that makes sense. If you look at the compiled python code for the example you sent, you can see that on each frame the custom keyboard kb is being checked first, followed by the keyboard component key_resp that was in the project. key_resp will consume / clear any keyboard events not first picked up by keyboard kb:

snippet from compiled code:

    keys = kb.getKeys(['f', 's'], waitRelease=False, clear=False)
    # Get and clear key when released
    keys_released = kb.getKeys(['f', 's'], waitRelease=True, clear=True)
        
    if keys:
        print("pressed: ", [(k.rt, k.name) for k in keys])
        
    if keys_released:
        print("released: ", [(k.rt, k.name, k.duration) for k in keys_released])
    
    # *key_resp* updates
    waitOnFlip = False
    if key_resp.status == NOT_STARTED and tThisFlip >= 0.0-frameTolerance:
        # keep track of start time/frame for later
        # ....
    if key_resp.status == STARTED and not waitOnFlip:
        theseKeys = key_resp.getKeys(keyList=None, waitRelease=False)
        # ....
