Hey,
we had the exact same problem while trying to beat this level twice in a row, but were suddenly able to beat it this way. Then we tried to replicate and film this bug (?) but were not able to reproduce it. So there is definitely a constellation of the random block model, the position of the red player, ..., but it is very unlikely to happen. So I recommend you to just try it again.
Best regards
Dominik
