Xtransciever sprite editing in B/W

[AriTheSmol]

I've been trying to change the blink cycle sprite for the player character so it's static (because I replaced the player sprite, and it doesn't line up and looks cursed). However, when I import the sprite into the rom and try to play it, when I reach the first xtransciever cutscene the screen turns black and stops responding. How do I fix this?

(Edited sprite is attached)
