Most likely cache updates.
Could you please (1) Set org-element--cache-self-verify to nil and see
if things get back to normal; (2) If things are still slow after setting
the variable, please run M-x profiler-start ... M-x profiler-report and
share the data. See https://orgmode.org/list/87ee2nlslt.fsf@localhost.
