This is a bug with the library itself, and not CraftOS-PC. It uses a top-level coroutine override, meaning that any errors that happen in the library (specifically, receiveEvents) will end up crashing the entire computer. I'm not sure exactly what the error is because none is being reported. You can attach a debugger and use catch error to make it break when the error occurs, then run the code and investigate further. Also, this code was built for an older version of ComputerCraft that may not be entirely compatible with CC: Tweaked 1.8x, so the bug may be caused by some change in CraftOS.
