While running the hardening role, I found that a small VM would regularly crash ansible on the chrony configuration templating task with "A worker was found in a dead state!". An ansible bug[0] shows that this can be caused by jinja templating that is not casted to the correct type. After verifying the crash was reproducible 3-4 times in a row, this crash stopped occuring once I started casting this variable to a bool. I don't know if it is coincidence but it can't hurt to cast this conditional regardless.
