You are correct. It’s the bracket at the top of the cam wire that breaks. The cause is the primer punch sticks in the upper position. As you cycle it (not knowing the punch is stuck up), the shuttle can not retract to pick up a primer. This puts pressure on the cam wire, breaking the bracket.
3 different punches. Cleaning it religiously. And it continues.
My current “work around” is that I have several replacements. As they get used, I’ll order more. Not ideal, but now it is primarily used for case prep.

Damn, why in gods name, when you feel that much resistance, do you try and bull through the stroke? After tens of thousands of rounds through a LnL, I've learned no good comes from forcing through a handle stroke when there is any significant resistance.
As far as the punch getting stuck in the up position, I've found that happens a lot if you are spilling powder, as grains get stuck in the punch, tying it up...I've also found that the punch can clip small pieces of cup material off the primer if the primer shuttle is the least bit out of alignment, usually caused by powder or primer fragments in the primer shuttle channel. Those chunks of primer do a wonderful job of tying up the primer punch. Also, you can lightly sand or buff the edges of the primer shuttle and primer punch so they don't catch on each other
