Im feelin lucky for this giveaway!

I bought an Ender 3 V2 about 6 months ago, and recently, it has stopped extruding. I tried unclogging the nozzle with the needle thing, but nothing happened. What I did notice is that the filament stepper motor gear was not pushing the filament. I tried tightening the bolt that made the gear push harder on the filament, but no luck. However, if I push the filament manually, it works fine. Any suggestions? (All settings are default and the bed is leveled correctly)

I was trying to print something after letting it sit for a week or two, but the extruder was putting out barely any filament. At first, I thought the nozzle was clogged, but I cleared it out with the needle thing that the printer came with. I didn't find any obstructions, so I tried printing the same thing again. This time, I realized that the extruder gear was not pushing the filament. If I push it manually, the filament flows fine, but if I let it do its thing by itself, then it won't grab onto the filament. I would believe that the gear had gotten dull, but I can't find any signs of the gear being worn down. I tried adjusting the screw that puts more pressure on the filament with the gear, but now I've tightened it all the way, and didn't make any difference. Help, please?
