I would suggest disabling "org persist" which has caused so much grief for me. (setq org-element-cache-persistent nil) Prior to me adding above line, I would get mysterious hangs, and all kinds of frequent errors. I tried debug-on-quit and debug-on-error, but this "org persist" thing was impossible to debug.
