Hello I've come across what seems to be a bug in org-element-cache handling.
To reproduce: 1) create a level 1 heading (in my case: "CAPTURE") and a level 2 heading (in my case: "CAPTURE-TEST") 2) create a similar template to file tasks under a level-2 heading: ("x" "Todo (test)" entry (file+olp "~/Workcloud/org/WORK.org" "CAPTURE" "CAPTURE-TEST") "* TODO %^{Task Description}" :prepend t) 3) create a task using this template (x) 4) while in the narrowed buffer, try to tag the task using C-c C-q (org-set-tags-command) This will hang. Pressing C-g helps you recover, the stack trace being Debugger entered--Lisp error: (quit) #f(compiled-function () #<bytecode 0x1321472668e93f>)() org-element--parse-to(77445) org-element-cache-map(#f(compiled-function (el) #<bytecode 0x184aaa442bea9805>)) org-get-buffer-tags() org-set-tags-command(nil) funcall-interactively(org-set-tags-command nil) call-interactively(org-set-tags-command nil nil) command-execute(org-set-tags-command) Disabling the cache with (setq org-element-use-cache nil) solves the problem. As does dropping "CAPTURE-TEST" in the template (i.e. putting the task under a level-1 heading instead of level-2).
