Golden Gnome Glitch *2021*

I am having a difficult time to get my last golden gnome collectible (right of the middle row on the shelf to the right when you walk into the gnome room). I’ve looked at multiple videos and images to see if I was doing things correctly, and I‘m sure i’m getting all of the golden gnomes in Great White North on a private/solo match. I was wondering if someone had any extra information or could contact me with my username on Xbox “Toiletzks9c9”. I know this question has been answered multiple times and still doesn’t seem to work in 2021, but I still hope someone can help me. Thank you.
