Printer extruder being nasty

I'm seriously at a loss. Few days ago i posted about this problem too. After about 30-40 ish minutes my prints start to fail. The extruder clicks and wont extrude. I can print really small prints like a benchy, but bigger and longer it wont. What i tried; changed to a new bowden tube (blue one) and cleaned it out and looked for any struggle when i put filament in, i changed to an aluminium extruder, changed the gears, tested different PLA spools, cleaned the whole hotend out (with the cold method where you decrease the temp to 100 c and clean it with 230 C), changed to a new nozzle, changed all the connectors for the tube hot end and the extruder, re leveled the bed, cleanded the extruder too, re calibrated e steps, tried a lower and hotter temp, changed the printing speed and changed the extruder tension.... I really dont know what to do. Filament always breaks in the extruder part and is squished with a bit of a black mark. I have an ender 3 v2 o yeah something i do notice is that the tube doesn't reach all the way to the nozzle.
