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.
