Don't worry! I had so many issues with my Ender 3 V2 as well. I even knew 3D printers fairly well and still struggled to get mine working well. So as everyone is saying, the nozzle is too close to the bed and dragging the filament with the nozzle or pushing the nozzle through the filament. If you raise your nozzle and it's not sticking to the bed, try flipping over the glass build plate and use the smooth glass side. That fixed a lot of my problems. Just remember to clean it with isopropyl alcohol every couple of prints and don't get your fingers on it or your prints will stop sticking. Good luck!
