I mean don't let them use the TP is probably going to be ur best bet. I know you can set up some like HML screen on the Tp so they can only do some stuff.
You should at least get a yellow prompt box on the TP which asks the user if they want to resume from that line. This may be a production check setting under Setup - Prog Select.
Regardless, this doesn't really help as it's just another step they can preform. You should be able to prevent access to the program with the password option. Alternatively, you could send a signal to the PLC when the TP is enabled and track it that way.
How are you starting the robot? If you are using UOP, then simply don't provide the operators with a resume button. If they turn the teach pendant on and off then you can force them to start the program over from the beginning.

It's a weird UOP/SOP combo. It's UOP signals controlled through flags so it can auto start after fence open/faults but if you press the sop start it will also pulse the start signal. But I don't want it to restart at the beginning because it's in the middle of loading a furnace and waiting for the signal drop the ingot, but they skip it and it loads the furnace anyway.
You can add a timeout to the wait and have it jump somewhere else. We stymie that by having the label that is jumped to turn on an output to trigger a red light, pause the program, and just have it jump back to itself so if they restart they are stuck in a loop. Savvy operators could still go up to the line it failed at and restart, but they'd have to know where to go.
I'm not sure if there is a way to prevent that systematically.
Even if you prevent fwd/bwd they can still press the up down arrows to put the cursor on a different line.
I say either lock the TP in a box, or monitor TP enabled in BG Logic or your PLC.
I had that same problem and I could not find a software solution.
So I hooked up a horn on the UOP tp enabled output.
Every time when the robot is in program and they switch on the tp, there is a 130 DBa sound resonating through the whole factory.
That helped.
Maybe remove access to the edit screen until logged in, or add several redundant checks and timeout loops with in the check program so it can be done with a single line skip
