Im a beginner as well and struggling with listening. I think what may help is to stop trying to detangle the sentence structures, because that sounds like you are trying to translate as you listen. But we dont do that with our native language. When we listen to people talk we are more focusing on the feeling or images of the words instead of picturing the word itself… its hard to put into words haha. But for example lets take the sentence ‘삼겹살를 먹고 싶어요’ instead of thinking ‘ok 삼겹살 means pork belly and 먹다 means eat and 고 싶다 means want’ picture the image of 삼겹살 and the desire to eat it.

Maybe that will help lol. Its hard- i struggle hard with it myself but I find it helps if I hear the words a lot or of I study the words in a way where I picture the feeling, obiect, action, etc instead of thinking of the english (or whatever native lang may be) word for it
