Does MC-248922 describe your issue?
In order to crawl, you must not already be obstructed in the feet, and have enough space. The lower causes not enough space for crawling, but will prevent going into crawling as it obstructs the area. The same can be seen with dropping blocks onto you, you won't enter crawling if the block space is obstructed.
