Saving the world while in crawl mining position makes you lose half a heart when you load back in.
Occasionally, you might suffocate and die until you mine the block above you.
How to reproduce:
Create a survival world.
Get a pickaxe (any type) and trapdoor. You may want a light source with you or night vision effect if you want to see better.
Dig down.
Go in crawl mining position.
Mine the blocks that are in front of you.
Save and exit the world.
Load back in.
Expected results:
No hearts lost and player may continue with mining.
Observed results:
Player will lose half a heart and in some cases, suffocate and die until the block above the player is removed.

Probably relates to BDS-18969
According to MCPE-188551 this causes ongoing suffocate on some platforms.
Could this be related to MCPE-180268? Maybe the player is switched out of the crawling position because the blocks above them have not fully loaded.
Sometimes, the player will continuously take damage.
