In addition to the info and files I sent over, I figured out a workaround that seems to be holding up. If I get more than 40 workers, and any of them run out of Stamina, a crash seems to follow. But, if I assign their work via the Worker Sanctuary and set the minimum Stamina threshold around 10-15%, they never hit 0, so no crash happens. Hope that helps anyone else who may be having this issue.
