can't sync anymore : Symbol’s function definition is void: twoway

Since upgrading to the latest org-mode from git (Org mode version 9.7-pre (release_9.6.3-340-g47d39c), attempting to sync with my google calendars fails with the following error. I'm using the latest org-caldav (20230331.11).

  twoway((twoway org->cal) #<buffer *org-caldav-debug*>)
  #<subr F616e6f6e796d6f75732d6c616d626461_anonymous_lambda_26>()
  funcall(#<subr F616e6f6e796d6f75732d6c616d626461_anonymous_lambda_26>)
  (let nil (funcall '#<subr F616e6f6e796d6f75732d6c616d626461_anonymous_lambda_26>))
  eval((let nil (funcall '#<subr F616e6f6e796d6f75732d6c616d626461_anonymous_lambda_26>)))
  org-caldav-sync-calendar()
  org-caldav-sync()
  funcall-interactively(org-caldav-sync)
  command-execute(org-caldav-sync)```

That's strange, I am also on latest org-mode from git, and not experiencing any problems with twoway sync (using Nextcloud).

From the trace, it's not obvious to me which part of org-caldav-sync-calendar is failing. Could you please do the following and report back:

1. Set org-caldav-debug-level to 2 and report output in *org-caldav-debug*
2. Check for any relevant output in *Messages*
3. M-x toggle-debug-on-error and run org-caldav-sync again, hopefully it will point to the specific line that crashes.

What's even stranger is that today, after a full reboot of the system, the problem has now disappeared, maybe there was some transient conflict between emacs, org and org-caldav versions. Thanks for looking into it. I'm closing it for now.
