<p>My 3D printer has got a clog, and i think it  is because the nozzle hole has just recently started to only screw in crooked. I’m not sure how this happened. I have tried with multiple nozzles, but they all screw in crooked. Is there a way to fix this? Or is my only option to get a new hotend.</p>

The technical term for this is "cross threading".

Note: if the threads on the heater block and /or nozzle have residual filament material on them it is easy to cross--thread the nozzle, especially when cold..   In this case it is easier to attach the nozzle with the heater hot so the filament material is soft.

You should be able to purchase only the heater block for your hot end. The nozzle should thread in by hand without undue force. Having to use a wrench at the outset is an indication of a problem which should have stopped the attempt.
