This is a known issue with ender 3, you have to put little clips into the bowden tube connectors to always keep tension on them otherwise the movement of the tube makes it come loose from the hot end. If the tube is not in perfect contact with the nozzle in the hot end then a gap forms which fills up with molten plastic and jams the filament from feeding like in the picture here >>1904135

I don't know why they still ship printers without these little clips or instructions to make them, it takes like 2 minutes to print them.

Your bowden tube is pretty damaged so you might as well replace it with capricorn tubing or just flip it around so the damaged end goes into the extruder instead of the hotend.
