I found this bug on Android Mcpe version 1.19.63. If a player stands on a double chest and opens a double chest they'll take damage. In my opinion the reason of damage could be that the chest isn't placed on two blocks but I didn't test it out just an assumption of mine.

When you eat something over a chest you "enter" the chest, your cheracter just permeates the chest when you eat

Yes there ware no mobs behind me I faced this bug about 5 or 6 times when saw the bug for the first time I thought it could be guardians but there was nothing.
I have reproduced this bug reliably.
If you place a chest in a hole with a 3 block hole (or more) beneath it. Then stand on the chest and open it you will take repeated fall damage and eventually die with the message "x fell from a high place".
I am on Windows 10 and Minecraft Bedrock 1.20
I have added a video.
This issue appears to occur specifically at the height of Y=63 or Y=62, and can be reproduced with a regular chest.
Are you sure there were no mobs behind you that were hitting you?
