Hi Ihor,
I tried to run that code but get errors for the elp-instrument-function calls
(both with my config and emacs -Q):
```
Debugger entered--Lisp error: (error "ELP cannot profile the function:
org-cite-basic--g...")
error("ELP cannot profile the function: %s" org-cite-basic--get-entry)
elp-instrument-function(org-cite-basic--get-entry)
(progn (elp-instrument-function #'org-cite-basic--get-entry))
elisp--eval-last-sexp(nil)
eval-last-sexp(nil)
funcall-interactively(eval-last-sexp nil)
command-execute(eval-last-sexp)
```
Best,
Jamie

Could you try the following:
1. Execute the following code:
(require 'elp)
(elp-restore-all)
(elp-instrument-function #'org-cite-basic--get-entry)
(elp-instrument-function #'org-cite-basic-activate)
(elp-instrument-function #'org-cite-basic--parse-bibliography)
(elp-instrument-function #'org-cite-basic--all-keys)
2. Open your org file where Emacs hangs
3. Run M-x elp-results
4. Report the ELP buffer contents here
Best,
Ihor
