Trial of chaos bag

Hello, I have already encountered a problem 5 times in Trial of chaos, that before passing the test stage, I accidentally jump onto the platform with the help of a blink, it goes down and that's it, if you stand on it, it does nothing, and you can't climb up, because there is an invisible wall. Please fix it, it's just a shame to lose the passage.https://imgur.com/a/4pyEdIb
