I've also noticed that the energy cell drop seems to freeze your character in this manner, and as far as I can tell I don't think it matters if you even have any of the options on but rather having the trainer activated at all appears to eventually cause the issue regardless.
I can confirm that as well. I'm actually seeing an error text at the top left of my game every time I activate the trainer now. Don't know why its doing it now of all times. Maybe there was some stealth update or something.
