That is because you're trying to jump off the platform upon entering. You should not jump, only walk. Once you jump once it gets you stuck and you have to re-enter.
I feel like it's part of the PQ, you struggle at the start as you're new to the interaction but once you know what to do it's not a problem anymore!
i feel that this should be on guide, so newbies like me would know or some sort , also please let me know if there is any other cwk bug/glitch or post for it
