I have a Samurai Z and tried to cause problems but was mostly successful loading.
I assume you tucked the tip of the film down under the orange line, down into the body towards the take-up spool.
I found one time the film didn't load when there was too much tension, or the cassette was a bit tilted. After closing the back I heard a slight buzz of the advance, but the film icon disappeared (not a blinking film). And the film didn't wind at all.
I moved the cassette around a bit and made sure film came out of the cassette easily, then it loaded properly.
