From the pic it looks like cross threading rather than over tightening. Always makes sure it threads smooth before you start tightening

Been there before. Thankfully, replacement blocks are pretty cheap.

I have a socket and extension I keep by the printer which fits the nozzle. That way I can screw it in by hand while hot, still easily feel if something is binding, and I don’t even have to burn off my fingertips.

maybe it’s hotend upgrade time then

Did the same with Trianglelab Dragon. Damaged the heatbreak as well when disassembling the hotend. Now I own a 1.8Nm torque wrench…
